Answer:

x= 12

Step-by-step explanation:

9x-20-4x=40

40+20=60

combine like terms

9x-4x=5x

divide 60 by 5

Find an equation of a line that has a slope 7 and passes through the point 3,11
choli [55]
You’re given that m=7 (slope is 7), so setup the slope-intercept form with that info: y = 7x + b.

Now you need to find b. Plug in (3,11) for x and y, x=3 and y=11.

11 = 7*3 + b

Notice the only variable left is b, so you’ll find b this way.

11 = 21 + b and then subtract 21 from both sides:

11 - 21 = b

-10 = b

Plug that back into the equation and you have y = 7x -10

G.O. HAS 3 ORANGE PICKS FOR EVERY 2 GREEN. IF THERE ARE 25 PICKS IN ALL, HOW MANY PICK ARE ORANGE?
Zanzabum

Answer:

There are 15 orange picks when we have 25 picks total

Step-by-step explanation:

orange: green    : total

3               2            5

We found the total by adding the orange and the green

We have 25 total picks

25/5 = 5

We need to multiply by 5 on everything to get to 25 picks

orange: green    : total

3 *5           2*5        5*5

15                10           25


There are 15 orange picks when we have 25 picks total
