Question

15 le 3/4(f+4)

Answer 1

\[15\leq \frac{3}{4}(f+4)\] multiply both sides by \(\frac{4}{3}\) to get
\[15\times \frac{4}{3}\leq f+4\]

Answer 2

what is \(15\times \frac{4}{3}\) ?

Answer 3

20?

Answer 4

yes
3 goes in to 15 5 times, and 5 times 4 is 20

Answer 5

so now we are looking at
\[20\leq f+4\] solve by subtracting 4 from both sides
what do you get ?

Answer 6

16, do I flip the signs?

Answer 7

no not when you subtract
only flip if you multiply or divide by a negative numbers

Answer 8

final answer should look like \(16\leq f\)
