4x/5 - 3x/7 = 4x/7 + 5x/7 can anyone please help with explanation...
Answers
Answer: x=0
Step-by-step explanation:
Multiply both sides of the equation by 35, the least common multiple of 5,7.
7×4x−5×3x=5×4x+5×5x
Multiply 7 and 4 to get 28.
28x−5×3x=5×4x+5×5x
Multiply −5 and 3 to get −15.
28x−15x=5×4x+5×5x
Combine 28x and −15x to get 13x.
13x=20x+25x
Combine 20x and 25x to get 45x.
13x=45x
Subtract 45x from both sides
13x−45x=0
Combine 13x and −45x to get −32x
−32x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since −32 is not equal to 0, x must be equal to 0.
X=0

Subtracting the first equation from twice the second, we get ...
2(2b +d) -(3b +2d) = 2(22) -(35)
b = 9 . . . . . . . . simplify
Then ...

1. How many triangles are created in the following situation:
Answers
Answer:
Step-by-step explanation:
We can use:
[tex]\frac{12}{sin35} = \frac{16}{sinB}[/tex]
Solve for sinB
[tex]sinB=\frac{16(sin35)}{12}[/tex]
The answer we get from that is: 0.76
With that answer, we can do:
[tex]B=sinx^{-1}(0.76)[/tex]
So, since the calculator did NOT put out an error, there is 2 such triangles.
Only 1 triangle can be formed by angle m∡A = 35°, a = 12, b = 16.
How many triangles are created in the following situation:m∡A = 35°, a = 12, b = 16. is to be determined.
The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°.
Here, the data given is m∡A = 35°, a = 12, b = 16,
Since one angle m∡A = 35° is given between the two sides a = 12, b = 16,.
There is only one triangle that can be made through the given data.
because when we plot the measures only one side can be added without calculation in order to complete the triangle.
Thus, only 1 triangle can be formed by m∡A = 35°, a = 12, b = 16.

You go to Ihop and order two servings of pancakes and a
-cup of coffee. The cost of the coffee is $2.00. You leave a
20% tip. The total bill is $14.40. How much does one serving
of pancakes cost?
Answers
Answer: $4.76
To find the answer you need to find out the total before the 20% tips to find this you need to subtract 14.40 and 20% which = $11.52.If the coffee was $2 you also need to subtract that so the equation would be (11.52-2.00=9.52).Lastly the question is asking you for the price of one serving of pancakes but we have the answer for 2 which is $9.52.To find the price of of 1 serving you need to divide $9.52 by 2 = $4.76.So your answer is $4.76 for 1 serving of pancakes.
Answer:
$4.76

find the number which when divided by 2/5 will give 30
Answers
Answer:
The answer is 12. 12 divided by 2/5 will give us 30.
Step-by-step explanation:
To find this, simply do the opposite of dividing. Simply multiply 2/5 by 30, and you'll have your answer.
First, before we do this, however, we are going to find out what the decimal form of 2/5 is. To do this, divide the numerator by the denominator. In this case, 2 is the numerator and 5 is the denominator. So divide 2 by 5.
This gives us 0.4. So 2/5 in decimal form is 0.4. Now multiply 0.4 by 30 to find your answer.
30*0.4=12
So the answer is 12. However, rememeber that you always need to check your work. So lets check.
12/30=0.4
0.4=0.4
Do we get a true statement? Yes, so we are correct.
The number you are looking for is 75.
To find the number that, when divided by 2/5, gives 30, we can set up the following equation:
x / (2/5) = 30
To solve this equation, we can multiply both sides of the equation by the reciprocal of 2/5, which is 5/2:
x = 30(5/2)
Simplifying the right side of the equation:
x = 150/2
Dividing 150 by 2:
x = 75
Therefore, the number you are looking for is 75.

Charlotte buys a ticket to go to a baseball game. The total includes a charge of 7% of the original price for extra fees. If Charlotte pays a total of $44.94, how much was the original price of the ticket?
Answers
Answer:
$41.7942
Step-by-step explanation:
First you need to change 7% into a decimal (you do this by dividing it by 100)
7÷100=0.07
Then, you multiply 0.07 with 44.94
0.07×44.94=3.1458
3.1458 is the amount for the extra fees.
After that, you subtract 44.94 with 3.1458
44.94-3.1458=41.7942
This gives us the original price, so, the original price is $41.7942.

Given equation is 2t/(t-5) + 1/(t-3) = 3
=> [2t(t-3)+1(t-5)]/(t-5)(t-3) = 3
=> (2t²-6t+t-5)/(t²-5t-3t+15) = 3
=> (2t²-5t-5)/(t²-8t+15) = 3
=> 2t²-5t-5 = 3(t²-8t+15)

Answer:
EF = 1.98
Step-by-step explanation:
Sin = opposite/hypotenuse; Cos = adjacent/hypotenuse ;
Tan = opposite/adjacent
DF = 4.5 which is the hypotenuse. So using the equation for Sin
Sin 26° = opposite/hypotenuse
Sin 26° = EF/4.5
.44 = EF/4.5 solving .44(4.5) = EF ; 1.98 = EF

The width of a rectangle is 3 yards less than its length. The perimeter is 130 yards. Find the length and width of the rectangle.
Answers
2L-6+2L=130
4L=136
L=34 W =31
Answer:
Length = 34 yards
Width = 31 yards
Step-by-step explanation:
Perimeter = 2(l + w), where l = length, and w = width
We know that w, is l - 3
130 = 2(l + l - 3)
130 = 4l - 6
136 = 4l
l = 34
Width is 3 less than 34, or 31

Write each equation in slope-intercept form. Under line the slope and circle the y-intercept in each equation.
5x+3y=30
This is one RSM
The y-intercept is (_,_)
Answers
Answer:
y = -5/3(x) + 10
Step-by-step explanation:
Slope intercept form is in the form of y = mx + b
M is the slope and b is the y-intercept.
We want to isolate the y in this equation so we subtract both sides by 5x and get.
3y = -5x + 30
Now we can divide both sides by three to leave y by itself.
y = -5/3(x) + 10
