Answer:
bags of snack = x = 6
bottles of water = y = 5
Step-by-step explanation:
The system of equations can be used to determine how many of each item they bought.
20.00=2.50x+1.00y
11=x+y
how many bags of snack mix did they buy?
Let
bags of snack = x
bottles of water = y
20.00 = 2.50x + 1.00y (1)
11 = x + y (2)
From (2)
x = 11 - y
Substitute x = 11 - y into (1)
20.00 = 2.50x + 1.00y
20.00 = 2.50(11 - y) + 1.00y
20.00 = 27.5 - 2.50y + 1.00y
20.00 - 27.5 = -2.50y + 1.00y
-7.5 = -1.5y
y = -7.5/-1.5
y = 5
Substitute y = 5 into (2)
11 = x + y
11 = x + 5
11 - 5 = x
x = 6
bags of snack = x = 6
bottles of water = y = 5
Step by Step:
Step 1.) Subract 10 from both sides.
Step 2.) Divide each side by one
answer: x=15
Answer:
Option D

Because, there is equals symbol in the equation.
Answer:
It will be x^7
Step-by-step explanation:
If a term doesn't have an exponet then it's considered 1. Then you're going to add all numbers which is, 1+2+4 which equals 7. So then that makes x^7.
