Answer:
The number is -100, Jill can think of something else, now.
Step-by-step explanation:
x = the number
x/4 - 20 = -45 {twenty less than one-fourth of the number is -45}
x/4 = -25 {added 20 to each side}
x = -100 {multiplied each side by 4}
-31.25
Jill's number=[1/4×(-45)]-20
=-11.25-20
=-31.25
{x | x<3 or x>1}
x+2<5
x<5-2
x< 3
x-7> -6
x> -6+7
x>1
