Let's set up an equation using w to represent the weekly allowance.
w/2 + 10 = 18
Then solve:
Subtract 10 from both sides
w/2 = 8
Multiply by two on both sides
w = 16
The answer is 16.

Let's set up another equation using c to represent the original number of candy.
(c - 3) ÷ 5 = 3
Solve:
Multiply by 5 on both sides
c - 3 = 15
Add three on both sides
c = 18
The answer is 18

Hope this helped! If you have any more questions or don't understand, please comment or DM me. :)

The measures of two supplementary angles are in the ratio of 1:4 what are the measures of the angles

vlabodo [156]

Answer:

Step-by-step explanation:

Supplementary always add up to 180 degrees.

so you can set up the equation like this:

1x+4x=180

5x=180

x=36

now to find the angle measures you plug in the value of x

one angle is 36 degrees and the other is 144 degrees

A can in the shape of a right cylinder is filled with 10W-40 oil. The weight of 10W-40 oil is 0.857 gram per cubic centimeter. I

disa [49]

First find the area of the cylinder using the following formula
$A = 2\pi rh + 2\pi r^2$
$A = (2 \times \pi \times 6 \times 10) + (2 \times \pi \times 6^2)$

After finding the area, <span>calculate the weight of the oil (in grams) in the can
</span>
weight in grams = A times 0.857
