a pizza place charges $15 for a pepperoni pizza and $12 for a cheese pizza. the goal is to sell $540 in pizza for the day. The situation can be represented by the equation 15x+12y=540, x=pepperoni pizzas and y= cheese pizzas. If the pizza place runs out of pepperoni, how many cheese pizzas must be sold to reach the daily goal?

System of equations that can be used to find the price of one drink and the price of one bag of popcorn is:
3d + 10p = 41
2d + 2p = 11
Price of a bag of popcorn is $ 3.5
Solution:
Let "d" be the price of one drink
Let "p" be the price of 1 bag of popcorn
Luke spends total of $41 on three drinks and 10 bags of popcorn
3 drinks x price of one drink + 10 bags of popcorn x price of 1 bag of popcorn = 41
3d + 10p = 41 ------ eqn 1
Christopher spend a total of $11 on two drinks and two bags of popcorn
2 drinks x price of one drink + 2 bags of popcorn x price of 1 bag of popcorn = 11
2d + 2p = 11 ------- eqn 2
Eqn 1 and eqn 2 represents system of equations that can be used to find the price of one drink and the price of one bag of popcorn
Let us solve eqn 1 and eqn 2 to find values of "d" and "p"
Multiply eqn 2 by 5
10d + 10p = 55 --- eqn 3
Subtract eqn 3 from eqn 1
3d + 10p = 41
10d + 10p = 55
(-) ------------------------
-7d = -14
d = 2
From eqn 2,
2d + 2p = 11
2(2) + 2p = 11
4 + 2p = 11
2p = 7
p = 3.5
Thus price of 1 bag of popcorn is $ 3.5 and price of one drink is $ 2

10(x−2)+15=8x+7
(10)(x)+(10)(−2)+15=8x+7(Distribute)
10x+−20+15=8x+7
(10x)+(−20+15)=8x+7(Combine Like Terms)
10x+−5=8x+7
10x−5=8x+7
Subtract 8x from both sides.
10x−5−8x=8x+7−8x
2x−5=7
Add 5 to both sides.
2x−5+5=7+5
2x=12
Divide both sides by 2.
2x/2 = 12/2
x=6

Peter has 36 ÷ 4; Peter has 9 model cars. Jade has 3 times as many as Peter; Peter has 1/3 as many as Jade, so 9 x 3 = 27, so Jade has 27 cars.
1st equation: 36 ÷ 4 = 9 -OR- 36 x 1/4 = 9
2nd equation: 9 x 3 = 27 -OR- (36 x 1/4) x 3 = 9
(36/4)3 = 9 would also work. I think the 1st equations would be best... just giving some choices...
hope this helped!

Answer:
Step-by-step explanation: plug 1/5 in for the "n", plug 6 in for the "y" and plug -3 in for the "c". This gives you 5 x 1/5 which equals 1. So now you have 1 times 6 which equals 6. Lastly you subtract 2(-3) which is -6. This results in 6 - (-6) which equals 12.
