Question

Which equation is solved by multiplying both sides by zero point five?

z divided by zero point five equals thirty

z plus zero point five equals thirty

zero point five times z equals thirty

z minus zero point five equals thirty

Answer 1

z/0.5 = 30 multiply by 0.5 z = 45
z + 0.5 = 30 subtract by 0.5 z = 29.5
z * 0.5 = 30 divide by 0.5 z = 15
