Equation: 2 (1/2x + 1) = -3 (2x - 1) +4 (2x + 1)

Answer Choices:

A. 5

B. All real numbers

C. No solution

D. None of the above

I got D but I wanted some confirmation. I feel like I got it wrong... Thanks!

Step-by-step explanation:

2(1/2x+1) = -3(2x-1)+4(2x+1)

Distributive Property 1x+2 = -6x+3+8x+4

Combine Like Terms. 1x+2 = 2x+7

Subtract 1x from both sides 2 = x+7

Subtract 7 from both sides -5 = x

Thus the solution is non of the above

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

0.32
