Question

I need help finding the values of each varabile

Answer 1

Answer:

It's easy

Step-by-step explanation:

Use the order of operations in reverse to isolate the variable on one side of the equation. The order of operations is PEMDAS -- parentheses, exponents, multiplication, division, addition and subtraction. When solving for a variable, use the order in reverse -- SADMEP.

Perform the opposite operation to what is called for in the equation. If the equation requires you to multiply, you will divide. If the equation calls for subtraction, you will add.

Repeat the same operation on both sides of the equation. In the area of the triangle example, you arrived at the formula 100=1/2 (20h). You want to get the “h” by itself on one side of the equation. Multiply both sides of the equation by 2 to counteract the effect of the “1/2.” You then have 200=20h. Divide both sides of the equation by 20 to isolate the “h.” You find out that h=10.
