Make a ratio, then cross multiply.
4/30=x/48
30x=4x48
30x=192
x=6.4
Answer: 12.5
Step-by-step explanation:
x/10 = 10/8
reduce the fraction with 2
x/10=5/4
simplify the equation using cross-multiplication
4x=50
divide both sides by 4
x=25/2
or
x=12.5
Answer:
x=4
Step-by-step explanation:
3x + 6 = 18
3x = 18 - 6 = 12
x = 4
Add the amount of choices, and divide by the number of customers surveyed.
