Four more than twice a number is less than negative eighteen. find all numbers that make this statement true.

You need to visualize this first. This in an equation would be 4+2x<-18. You first subtract -4 to both sides. This would give you 2x<-22. Then you divide both sides by 2 to get x<-11. So any number less than -11 would work. This means that -12, -13, -14 and soon would work for x

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
