Answer 1

Tell me if I'm right? x is less than or equal to 20? thats what i got

Answer 2

Okay, so here's what you do:

Answer 3

\(\frac{x}{4} + \frac{x}{5} \le \frac{9}{1}\)

Answer 4

ok

Answer 5

Multiply 9/1 by 5/5 to get:

\(\frac{x}{4} + \frac{x}{5} \le \frac{9}{1} \dot\ \frac{5}{5}\)

Answer 6

Simplify that, then subtract x/5 from both sides

Answer 7

Is it x/4=5

Answer 8

<**

Answer 9

No, you have to multiply the right side

Answer 10

You know how to multiply fractions right?

Answer 11

i multiplied it and got 5

Answer 12

You multiplied \(\frac{9}{1} \dot\ \frac{5}{5}\) and got 5?

Answer 13

no 9

Answer 14

The point is to multiply and get 45/5

Answer 15

you need two fractions with the same denominator in order for this to work

Answer 16

When you subtract x/5 from both sides you should get:

\(\frac{x}{4} = \frac{45}{5} - \frac{x}{5}\)

Answer 17
