Answer:

C = 5/8 (F - 32)

C × 8 = 5/8 × 8 (F - 32)

8C = 5(F - 32)

$\frac{8C}{5} = \frac{5(F - 32)}{5}$

$\frac{8C}{5}$ = F - 32

$\frac{8C}{5} + 32$ = F - 32 + 32

$\frac{8C}{5} + 32$ = F

C = 22

F = $\frac{8C}{5} + 32$

F = $\frac{8(22)}{5} + 32$

F = $\frac{176}{5} + 32$

F = 35.2 + 32

F = 67.2

nikdorinn [45]

Answer:

2.8(10^13)

(10^5) TIMES (10^7) equals 10^12 (add the exponents 5 and 7 together)

Final answer: 28.0(10^12), or, better yet, 2.8(10^13)
