19. v/2 = 2 1/30

Turn mixed number(s) to improper fraction(s).
v/2 = 61/30

Multiply both sides by 10.
v/2 × 10 = 61/30 × 10

Simplify.
5v = 61/3

Divide both sides by 5.
5v ÷ 5 = 61/3 ÷ 5

Simplify.
v = 61/15

61/15 or if you want it as a mixed fraction, it would be 4 1/15.

Mariana solved the equation below. Identify her ERROR and EXPLAIN what she did wrong. -3(2x-4)=-12 -6x-12=-12 -6x=0 x=0
nydimaria [60]

Answer:

Her error was multiplying -3 and -4 which gives +12 but she wrote -12 instead

Step-by-step explanation:

Mariana workings:

-3(2x - 4) = -12

-6x - 12 = -12

Her error was multiplying -3 and -4 which gives +12 but she wrote -12 instead

-6x = 0

x=0

Correct workings:

-3(2x - 4) = -12

-6x + 12 = - 12

-6x = -12 - 12

-6x = -24

x = -24/-6

x = 4
