Write the word sentence as an equation. then solve. the quotient of a number x and −1.5 is 21

x / -1.5 = 21 and x =

Step-by-step explanation:

x / -1.5 = 21                -Multiply both sides by -1.5

x = -31.5

Check:

-31.5 / -1.5 = 21

21 = 21

Hope this helps you!

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
