Question

I need help on this 6th grade math problem

Answer 1

Answer: B) 12.5

Explanation:

Start by isolating x by subtracting 2.5 from both sides

`x+2.5 < 20\\x+2.5-2.5 < 20-2.5\\x < 17.5`

This reads as "x is less than 17.5"

D can be eliminated because it is greater than 17.5

C can be eliminated because 17.5 can't be less than itself

So the answer must be B since it is less than 17.5 and greater than A

Answer 2

Answer: x<17.5

Explanation:

Subtract from both sides: x+2.5-2.5<20-2.5

Simplify the arithmetic: x<20-2.5

Simplify the arithmetic: x<17.5

Hope it helps!
