Answer:
x=7
Step-by-step explanation:
16x-8x-12= 24+20
(16x-8x)-12= 24 +20
8x - 12= 24 +20
8x = 24+ 20 + 12
8x = 54
x = 54/8
x= 7
Answer:
x=7
Step-by-step explanation:
1. combine like terms
2. isolate x
3. divide by 8 to get x
The price of a ring was increased by 30% to £325. What was the price before the increase?
Please answer asap!!
Answer:
227.5
Step-by-step explanation:
Find the number that is increased by 30% to get to 325.
100-30 = 70.
In other words, what number is 70% of 325.
325 x .70 = 227.5
The original price of the ring was 227.5.
Check your work, 227.5 = 70% of X
227.5 / .70 = 325
Answer:
The cost before the increase is £250.
Step-by-step explanation:
Given that after 30% increases, the cost of the ring is £325 so we can assume that 130% is £325. Now, we have to form an expression in term of x where x represents the original cost :
[tex] \frac{130}{100} \times x = 325[/tex]
Next, we have to solve it :
[tex]x = 325 \div \frac{130}{100} [/tex]
[tex]x = 325 \times \frac{100}{130} [/tex]
[tex]x = 250[/tex]

3/5(5) = 3
3/5(10) = 6
Step-by-step explanation:
Sub the x (domain) into the equation and solve.
Answer:
x (0) = y (0)
x (5) = y (3)
x (10) = y (6)
Step-by-step explanation:
You substitute the given x in the table into the equation.
For example:
y= 3/5 (0)
= 0
Use the image below to solve for x.
Answer:
x will equal 61 degrees
Step-by-step explanation:

5. A restaurant orders 132 bags of flour. Each box contains 4 bags of flour. Write an equation that
you can use to solve x the number of boxes they receive. Solve the equation.
132/4 = 33, x = 33 boxes
Answer:
4x=132
you divide by 4 on both side
x should be by it self
x=132/4
x=33
If you want make a harder equations use this
4x+10=142
subtract 10 9n both side
-10+10 +4x= 142-10
4x=132
divide by four on both side
x=132/4
x=33

(3x+4y=18) (5x+6y=28)
Answer:
x = 2, y = 3
Step-by-step explanation:
Given the 2 equations
3x + 4y = 18 → (1)
5x + 6y = 28 → (2)
Multiplying (1) by 5 and (2) by - 3 , then adding will eliminate the term in x
15x + 20y = 90 → (3)
- 15x - 18y = - 84 → (4)
Add (3) and (4) term by term to eliminate x
2y = 6 ( divide both sides by 2 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
3x + 4(3) = 18
3x + 12 = 18 ( subtract 12 from both sides )
3x = 6 ( divide both sides by 3 )
x = 2
Solution is (2, 3 )

Find and interpret the slope of the line containing the given points. (0,20) and (-8,0)
Answer:
The slope is: 20/-8, or -20/8
Step-by-step explanation:
to find the rate of change, you do change in y over change in x
so you minus the y numbers and minus the x numbers
so,
20-0/0-8 = 20/-8
or you can do
0-20/8-0 = -20/8
both of them are the same

What is the system of solutions?
a house with an original value of $210,000 increased in value to $300,000 in 5 years what is the ratio of the increase in value to the original value of the house ?
Answer:
6%per year
Step-by-step explanation:
210000/300000=.7
it increased by 30%
30/5=6%per year
The ratio of the increase to the original will be 0.43.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Original value = $210,000
Final value = $300,000
Increment = 300000 - 210000 = 90000
The ratio of increment to original
⇒ 90000 / 210000 = 0.43
Hence "The ratio of the increase to the original will be 0.43".

Which point-slope equation represents a line that passes through (3,-2) with a slope of -4/5
O y-3 =-4/5(x+2)
Oy - 2 =4/5(x-3)
Oy+2=-4/5(x-3)
O y + 3 = 4/5(x+2)
Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point

what is the quotient of a number and 5
Sorry but that's an unclear question, can you double check to see if you included everything, and also check to see the possible answers?
help me please!!!!!!!
Answer:
C (-6,-8) → C' (6,8)
D (-2,-8) → D' (2,8)
E (-2,-4) → E' (2,4)
F (-6,-4) → F' (6,4)
Step-by-step explanation:
When you rotate a point 180° counterclockwise about the origin, the point A (x,y) becomes A' (-x,-y). So, if the points are positive, they will become negative.
Because all the points are negative, rotating them 180° counterclockwise will make them positive.

Ann's Paycheck showed a regular weekly salary of $835.50 a deduction of 13.29 a bonus of 34.35 and 28.95 for overtime. what is ANN's final pay?
Answer:
$885.01
Step-by-step explanation:
Answer:
$885.51
Step-by-step explanation:
$835.50-$13.29= $822.21
-The first step is to subtract the deduction. Deduction always means subtract.
$822.21+$34.35= $856.56
-Once you get the new total by subtracting the deduction, you have to add the bonus. Bonus always means add.
$856.56+$28.95= $885.51
-Finally, when you work overtime at a job, your employer is required by law to pay you extra. Add the overtime and get the final total of $885.51.

The angles in a triangle are in the ratio 1:2:3. Show that this triangle is a right-angled triangle. The hypotenuse of the triangle is 19 cm long. Calculate the length of the shortest side in the triangle
Answer:
see explanation
Step-by-step explanation:
(a)
Sum the parts of the ratio , 1 + 2 + 3 = 6 parts
Divide sum of angles in a triangle by 6 to find the value of one part of the ratio.
180° ÷ 6 = 30° ← value of 1 part of the ratio
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
Since there is an angle of 90° then the triangle is right.
(b)
The shortest side is the side opposite the smallest angle of 30°
Using the sine ratio and the exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opp}{hyp}[/tex] = [tex]\frac{opp}{19}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2 opp = 19 ( divide both sides by 2 )
opp = 9,5
Shortest side in the triangle is 9.5 cm
