Question

1- 10(1+3b)=-20

Answer 1

Answer:

(number one) b = 11/30

(number two) v= -23/15

Step-by-step explanation:

(number one) 1- 10 (1+3b)= -20 (distribute)

-1-10-30b = -20 ( add the like terms)

-9 - 30b = -20 (move -9 to the right)

-30b = -20 + 9 (calculate)

-30b = -11 (divide)

b = 11/30

(number two) 2-6(1-5v) = 54 (change the negative to a positive)

2+6 (1-5v) = 54 (distribute)

2+6-30v= 54 (add the like terms)

8- 30v = 54 (move 8 to the right)

-30v = 54-8 (subtract the number)

-30v = 46 (divide)

v = -46/30 (reduce the fraction)

v= -23/15
