Answer:
It would be B (15x + 20x)
52=100%
x=30%
52/x=100%/30%
which equals to 15.6
Answer 15.6
Answer:
Part A, one solution
Part B, x=3
Step-by-step explanation:
divide both sides of the equation by 7 (5x-13=2)
move the constant to the right hand side and change its sign (5x=2+13)
add numbers (5x=15)
divide both sides of the equation by 5 (x=3)
