Solve: 3[-x+(2x=1)]=x-1 I can't distribute so I don't know what to do.

Nat2105 [25]

Answer:

Below

Step-by-step explanation:

● 3 ( -x +2x - 1) = x - 1

● 3 ( -x -1 ) = x - 1

● -3x -3 = x - 1

Add -x to both sides

● -3x -3 - x = x -1 -x

● -4x -3 = -1

Add 3 to both sides

● -4x - 3 + 3 = -1 + 3

● -4x = 2

Divide both sides by -4

● -4x/-4 = 2/-4

● x = -1/2

You have been keeping track of the outside temperature for a class project.

poizon [28]

The percent change between the temperature at noon and the temperature at 5:00 p.m. is -20%

The percent change is the relative change between two quantities expressed in percentage.

Given that the At noon, the temperature was 80°F while At 5:00 p.m., the temperature was 64°F. Hence:

Percent change = [(64°F - 80°F) / 80°F] * 100%

Percent change = -20%

Therefore the percent change between the temperature at noon and the temperature at 5:00 p.m. is -20%
