What is the percent of 792 and 1,220

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 1220 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 1220, so we can write it down as 100%=1220.

4. We know, that x% equals 792 of the output value, so we can write it down as x%=792.

5. Now we have two simple equations:

1) 100%=1220

2) x%=792

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=1220/792

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 792 is what percent of 1220

100%/x%=1220/792

(100/x)*x=(1220/792)*x       - we multiply both sides of the equation by x

100=1.540404040404*x       - we divide both sides of the equation by (1.540404040404) to get x

100/1.540404040404=x

64.918032786885=x

x=64.918032786885

now we have:

792 is 64.918032786885% of 1220

Step-by-step explanation:

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
