Answer:
y=0.75x+5
Step-by-step explanation:
x=20
y=20
20-5=15
15/0.75=20
20 games
2. I think the answer is 24
subracting the last 2 inequalities we get
6x + 7y <= 42
3x + 2y <= 18 subtract:_-
3x + 5y <= 24
You use distributive property. So (5 x 2)-(5 x x)= 10 - 5x.
F(n)=3n-2
Plug in 2 for n. f(2)=3(2)-2=4
Answer:
50 combos
Step-by-step explanation:
Put it into an equation first in order to find x.
2x + 250 = 7x
Subtract 2x from both sides.
250 = 5x
Then divide both sides by 5.
x = 50
Therefore you need 50 combo meals in order to make the amount made equal to the amount paid.
<u>You can check your work by plugging in the number to both.</u>
$250 plus the $2 times 50 combo meals.
250 + 2(50) = 350
$7 times 50 combo meals
7 x 300 = 350
