Answer:

17.6 minutes

Step-by-step explanation:

$\frac{4}{5} = \frac{x}{22}$

$5x=22$

$x=\frac{22}{5}$

$4(\frac{22}{5} ) = \frac{88}{5} = 17.6$

5/6*2/3 9/10*5/18 4/5*3/4 2/3*5/1

To multiply fractions, you multiply numerator with numerator and denominator with denominator

In other words: a/b*c/d=(a*c)/(b*d)

So 1st one is (5*2)/(6*3) which is 10/18 or 5/9 simplified

2nd one is (9*5)/(10*18) which is 45/180 or 1/4 simplified

3rd one is (4*3)/(5*4) which is 12/20 or 3/5 simplified

4th one is (2*5)/(3*1) which is 10/3 or 3 1/3 if you want a mixed number

Hope this helped!

Answer:

The answer is A) y = -7x - 7.

Step-by-step explanation:

First, you need to subtract '7x' from both sides, and once that is done, the equation is in slope-intercept form because it is in y=mx+b form. I'll attach a photo below that explains my process! :) And another possible answer would be y = 7x + 7, but that is not an option listed above.
