Plzzzzz help meeEEEE ALL 3 REWARD BRAINLIESTT
Fittoniya [83]

Answer:

See below

Step-by-step explanation:

1. (refresh if you cant see it)

F = \frac{9}{5}C+32\\\text{Bring variable C to left side}\\-\frac{9}{5}C=-F+32\\\text{Multiply by -1}\\\frac{9}{5}C=F-32\\\text{Multiply the equation by 5/9 to get C by itself}\\C = \frac{5}{9}(F-32)

2.

2(x + 3) = 20

Distribute.

2x + 6 = 20 \neq 2x + 3 = 20

Your answer is false.

3.

x \geq -2 because even though it includes the expression "x>5", those values are also above -2, including 5.
