Answer:
4 [tex]\frac{1}{6}[/tex]
Step-by-step explanation:
When adding fractions, you want to make the denominators of the fraction the same. To do this, we can multiply both the numerator and denominator of 3/4 by 3. When changing either a denominator or numerator in a fraction, you must do the same thing to the numerator as the denominator.
Now we have [tex]\frac{3\cdot3}{4\cdot3} = \frac{9}{12}[/tex]. To add 9/12 and 5/12, we keep the denominator the same, and add the numerators, getting [tex]\frac{9+5}{12} =\frac{14}{12}[/tex]. This is greater than 1, so we can take 12/12 from 14/12, and make it [tex]1 \frac{2}{12}[/tex]. If we then add 3, we get [tex]4 \frac{2}{12}[/tex], which simplifies to [tex]4 \frac{1}{6}[/tex]

3x - 4 + 6x = -31
17 = 3x - 10
2x + 6 = 4x - 8
17x - 5(3x - 11) = 41
5x - (3x - 6) = 18
6x - 3(4 - 5x) = 30
x - (-5) = 7
This is a lot of questions-
I did them all on a calculator.
1.)
3x - 4 + 6x = -31
3x + 6x - 4 = -31
9x - 4 = -31
9x = -27
Answer: x= -3
2.)
17 = 3x - 10
3x -10 = 17
-10 = -10
3x = 27
divide both sides by 3
Answer: x= 9
3.)
2x + 6 = 4x - 8
-6 = -6
2x = 4x -14
-4x (both sides)
-2x = -14
divide both sides by -2
Answer: x = 7
4.)
17x - 5(3x - 11) = 41
2x +55 = 41
-55 (both sides)
2x = -14
divide 2 both sides
Answer: x = -7
5.)
5x - (3x - 6) = 18
2x + 6 = 18
-6 both sides
2x = 12
divide both sides by 2
Answer: x = 6
6.)
6x - 3(4 - 5x) = 30
21 - 12 = 30
+12 boh sides

Jack's birthday is in 8 weeks. How many days is it until Jack's birthday? Complete the explanation on how you could use a number line to solve. Jack's birthday is in days. I would draw equal jumps of beginning at 0 on the number line. The jumps end at .
Answer:
Jack's birthday is in 56 days.
The jumps end at point 56 on the number line.
Step-by-step explanation:
Since one week has 7 days.
So, 8 week = 8 x 7 =56 days.
Hence, Jack's birthday is in 56 days.
On the number line, the current time is being represented by 0.
When I take one jump from 0, I will reach the point 1 on the number line, which corresponds to 1 day.
Again, in my 2nd jump from point 1 on the number line, the next point on the number line will be 2 which corresponds to 2 days.
This process repeats until I complete the 56 jumps to get point 56 on the number line, which corresponds to 56 days.
In this way, the number line can be used to solve.
Hence, the jumps end at point 56 on the number line.

Answer:
Area of original shape: x1
Area of zoomed shaped: x4
Perimeter of original shape: x1
Perimeter of zoomed shaped: x2
Step-by-step explanation:
Since the image is zoomed in by 2, it means that all measurements are doubled. When calculating the area, the zoomed shape had an area 4 times greater than the original shape! With perimeter, instead of the same multiplier, the perimeter of the zoomed shape was only doubled of the original shape.
Rohini spends 88℅ of her monthly income. If she saves rs 3420 per month,what is her monthly income ?
Answer:
rs 28500
Step-by-step explanation:
If she saves rs3420 and spends 88% we need to convert 88% to a decimal first.
88% = 88/100 = .88
Let m equal her monthly income.
m - .88m = 3420
.12m = 3420
.12m/.12 = 3420/.12
m = 3420/.12
m = 28500
He monthly income is rs28500.

One crate can store 12^3 toys. A warehouse receives 12^7 toys. Enter the number of crates
needed to store all the toys the warehouse received.
Answer: The number of crates needed to store all the toys the warehouse received = [tex]12^4= 20736[/tex]
Step-by-step explanation:
Given: Total number of toys = [tex]12^7[/tex]
Number of toys in one crate = [tex]12^3[/tex]
The number of crates needed to store all the toys the warehouse received.
= (Total number of toys) ÷ (Number of toys in one crate)
[tex]=12^7\div 12^3 = 12^{7-3}\ \ \ [a^m\div a^n=a^{m-n}]\\\\=12^4[/tex]
Hence, the number of crates needed to store all the toys the warehouse received = [tex]12^4= 20736[/tex]
Answer:
12^4 or 20736
Step-by-step explanation:
Since the warehouse has 12^7 toys and you need to find how much crates that can fit 12^3 toys will store all the toys, you must divide 12^7 by 12^3.
When dividing radical expressions, remember:
a^3/a^2=a^1 This kind of acts like subtracting the squared number
a^3 * a^2 = a^5 This kind of acts like adding the squared number
(a^3)^2 = a^6 This kind of acts like multiplying the squared number
Therefore, if you use the methods above, 12^7 / 12^3 = 12^4
12^4= 20736

Hank wants to add a row of tile to his kitchen wall. The space is 5.75 feet long. He plans to put a \frac {3}{4} 4 3 –foot yellow tile in the center. He'll fill the rest of the space with blue tiles that are 3 inches long. How many 3-inch blue tiles will he need?
Answer:
He will need 20 3-inch blue tiles
Step-by-step explanation:
Here, the total space to fill is a length of 5.75 ft
The tiles to place at the center has 3/4 ft which is same as 0.75 ft
The length left unfilled will be 5.75 - 0.75 = 5 ft
Now we want to know the number of 3 ft tiles needed to fill up this length;
Mathematically, we know that
1 ft = 12 inches
So 5 ft will be 5 * 12 = 60 inches
So the number of 3 inch tiles needed to fill this length will be 60/3 = 20 tiles
Kelly needs to travel 12 miles. Taxi A charges $3.00 plus $0.30 every 1/9 mile. Taxi B charges $3.25 plus $0.20 every 1/9 mile. How much money (in dollars) does kelly save by using taxi B instead of taxi A? (PLEASE HELP ASAP)
Answer:
$10.55
Step-by-step explanation:
Total miles traveled = 12miles
If taxi A charges $0.3 for every 1/9 mile, then for 12 Miles, he will charge;
12×0.3/(1/9)
= 12×0.3×9
= 108×0.3
= $32.4
Amount charged initially = $3.00
Total charge by Taxi A = $32.4+$3.00
Total charge by Taxi A = $35.4
If taxi B charges $0.2 for every 1/9 mile, then for 12 Miles, he will charge;
12×0.2/(1/9)
= 12×0.2×9
= 108×0.2
= $21.6
Amount charged initially = $3.25
Total charge by Taxi B = $21.6+$3.25
Total charge by Taxi B = $24.85
Total money saved by Kelly = Amount charged by Taxi A - Amount charged by Taxi B
Total money saved by Kelly = $35.4-$24.85
= $10.55
Hence Kelly saved $10.55 using taxi B

Which of the following graphs shows the solution set to t > 4 or t < -1?
Answer:
The second graph
Step-by-step explanation:
t is greater than 4 and less than -1 but doesn't include the points 4 and -1 (thus the open circles)
The second graph represents the solution set to t > 4 or t < -1.
What are open and closed interval ?In open interval we do not include the point and represented by open circle in close interval we do include the points and represented by closed interval.
According to the given question we have to determine which graph represents the solution set t > 4 or t < -1.
We know when we represent less than or greater than in the number line we represent it as an open circle.
So, t > 4 will be represented by an open circle on the number line starting at 4 but not including which goes to positive infinity and t < -1 will be represented by an open circle at -1 not including which goes to negative infinity.

−24 − (18 ÷ 6) × (−12)
Answer:
12
Step-by-step explanation:
Answer:
The expression is equal to 12.
Step-by-step explanation:
[tex]-24-(18 / 6)*(-12)[/tex]
First of all, compute the parenthesis.
18 / 6 = 3
Now, replace 18/6 with 3 in our expression.
[tex]-24-(18 / 6)*(-12)[/tex]
[tex]-24-(3)*(-12)[/tex]
Next, compute the multiplication.
-12 * 3 = -36
Again, we'll replace that multiplication with negative 36:
[tex]-24-(3)*(-12)[/tex]
[tex]-24-(-36)[/tex]
Since subtracting a negative number is the same as adding a positive number:
[tex]-24-(-36) = -24+36[/tex]
Compute the addition:
[tex]-24+36=12[/tex]
[tex]-24-(18 / 6)*(-12) = 12[/tex]
Answer: The expression is equal to 12.

The 240 ninth-graders at a high school are divided into homeroom groups of 10 or 12 students. This equation models the
situation, where x represents the number of 10-student groups and y represents the number of 12-student groups:
10x +12y = 240.
? Question
Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar.
The x-intercept is located at ( ,0).
The y-intercept is located at (0, )
The slope of the line represented by this equation is[ ]
Answer: The X intercept is located at (24,0) The Y intercept is located at (0,20)
The slope of the line represented by this equation is -5/6
Step-by-step explanation:
The x-intercept is located at (24, 0).
The y-intercept is located at (0, 20)
The slope of the line represented by this equation is (-5/6).
We have,
Equation:
10x + 12y = 240
This can be written in the slope-intercept form.
y = mx + c
Where m is the slope and c is the y-intercept.
Now,
10x + 12y = 240
12y = 240 - 10x
12y = -10x + 240
y = (-10/12)x + 240/12
y = (-5/6)x + 20
Now,
The y-intercept is 20.
This is when x = 0.
And,
The x-intercept is when y = 0.
0 = (-5/6)x + 20
(5/6)x = 20
x = 4 x 6
x = 24
And,
The slope is (-5/6)
Thus,
The x-intercept is located at (24, 0).
The y-intercept is located at (0, 20)
The slope of the line represented by this equation is (-5/6).
