Answer:
Multiplying the variables and numbers in the parentheses by the number next to them.
Step-by-step explanation:
To answer this question you will set up a system of equations to represent each scenario. Solve for one variable and substitute that in to the other equation to find the missing value. This example will have you solving for p, the price of popcorn.
4p + 3s = 13.50 and 2p + 5s = 12
2p + 5s = 12
-2p -2p
5s = 12 - 2p
5 5
s = 2.4 - 0.4p
4p + 3s = 13.50
4p + 3(2.4 - 0.4p) = 13.50
4p +7.2 - 1.2p = 13.5
2.8p +7.2 = 13.5
-7.2 -7.2
<u>2.8p</u> = <u>6.3</u>
2.8 2.8
p = 2.25
The price of popcorn is 2.25 and the soda is (2.4 - 0.4 x 2.25) $1.50.
5 popcorn and 2 sodas will cost (2.25 x 5 + 1.50 x 2) = $14.25.
I think it’s the first one.
2/3 rds of 6=4
And the division between the 2 variables equals this number
