Answer:
See below
Step-by-step explanation:
1. (refresh if you cant see it)
[tex]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)[/tex]
2.
2(x + 3) = 20
Distribute.
2x + 6 = 20 [tex]\neq[/tex] 2x + 3 = 20
Your answer is false.
3.
x [tex]\geq[/tex] -2 because even though it includes the expression "x>5", those values are also above -2, including 5.
