Answer: Inequality: 175+2x/5 ≥ 500. He must make $812.5 or more in his paycheck

Step-by-step explanation:

175+2x/5 ≥ 500

2x/5 ≥ 500-175

2x/5 ≥ 325

2x ≥ 325*5

2x ≥ 1,625

x ≥ 1,625/2

x ≥ 812.5

First rewrite 8/25 and 7/20 so that they have a common denominator
Pie

Answer:

  • 8/25 = 32/100
  • 7/20 = 35/100

Step-by-step explanation:

25 and 20 have a least common multiple of 100, so that is your least common denominator.

  8/25 = (8·4)/(25·4) = 32/100

  7/20 = (7·5)/(20·5) = 35/100
