Which expression is the factored form of−1.5w+7.5?

a. −1.5(w−5)

b. 1.5(w−5)

c. −1.5(w+5)

d. 1.5(5+w)

-2x+3(-5x+1)=-2x+(-15x+3)

=-2x-15x+3

=-17x+3

-5/3a+1/8-1/6a-1/2=-5/3a-1/6a+1/8-1/2

=-40/24a-4/24a+3/24-12/24

=-44/24a-9/24

=-11/6a-3/8

3(1/5x-1/7)=3/5x-3/7

Hence, ans: C

-1.5w+7.5=1.5(-w+5)

=-1.5(w-5)

Hence, ans: A

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
