Given the line -9x-6y=18. Find the slope
SashulF [63]

Answer:

slope = - \frac{3}{2}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange - 9x - 6y = 18 into this form

Add 9x to both sides

- 6y = 9x + 18 ( divide all terms by - 6 )

y = - \frac{3}{2} x - 3 ← in slope- intercept form

with slope m = - \frac{3}{2}

If the ratio of men to women is 3:2 and there are 120 men, how many women would there be?
zavuch27 [327]
There would be 80 women.
Here's the work:
120 divided by 3 = 40 
If the ratio is 3:2, there is always one less woman then men, so you subtract the 40 men in a group and you get your answer of 80

Hope I helped!! :)

Olin [163]
I got 16.8 , but she’ll need roughly 17 gallons of paint :)

how i did it :

1. so you know she’ll need 4/5 per book case, and there are 16 bookcases.
2. So you do 16 x 5, then you get 84
3. and you divide 84 by 5. and you’ll get 16.8, that’s how many gallons of paint she needs
