Which expression shows the result of applying the distributive property to 3(1/5x−1/7)?

a. 3/5x+3/7

b. −3/5x−3/7

c. 3/5x−3/7

d. −3/5x+3/7

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

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
