Answer:

Sum of 487 would be 490 if rounded to the next whole number and 500 if rounded to the whole number.

So 490+300 = 790 OR 500+300=800

Hope that was helpful.Thank you!!!

ELEN [110]

Answer:

F = $\frac{9}{5}$ C + 32

Step-by-step explanation:

Given

C = $\frac{5}{9}$ (F - 32)

Multiply both sides by $\frac{9}{5}$ to clear the fraction

$\frac{9}{5}$ C = F - 32 ( add 32 to both sides )

$\frac{9}{5}$ C + 32 = F
