Answer:
6p - 2q
Step-by-step explanation:
(2p + 6q) + (4p - 8q)
= 2p + 4p + 6q - 8q
= 6p - 2q
The temperature fell by 24 degrees in 6 hours. We need to find out how many degrees did the temperature fall every hour.
You can <u>divide</u> 24 with 6.
24 ÷ 6 = 4
Your answer is 4
hope this helps!

Answer:
360
Step-by-step explanation:
Sam obtains a "contribution margin" of $0.50 -0.25 = $0.25 per cookie. That will cover the cost of baking supplies when he sells ...
$90 / ($0.25/cookie) = 360 cookies
Sam needs to sell 360 cookies before he can start making a profit.
_____
If you like, you can find Sam's break-even point by equating revenue and cost. The is the number of cookies Sam must sell for a profit of 0, that is, for non-negative profit.
P = R - C
0 = R - C
R = C
0.50n = 90 +0.25n
0.25n = 90 . . . . subtract 0.25n
n = 90/0.25 = 360 . . . .divide by the coefficient of n
You may notice this is similar to our description above.
It is Irrational because is can not be written as a fraction
