Answer:
3/4 = z
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
Divide 3 by 4, then subtract z from the result
3/4 - z
<u>Step 2: Solve for z</u>
3/4 - z + z = 0 + z
3/4 = z
Answer: 3/4 = z
let x = a number
difference means that its subtraction
twice a number is 2x
so the equation should be
2x-5=3
add 5 to both sides
2x=8
divide both sides by 2
x=4
For a you need to do (10 times 13) plus (10 times 7) because there's two boxes one is shaded.
For b you need to do (7.5 times 20) plus (2.5 times 20)
