Answer: i try my best to do
Step-by-step explanation:
4(.75) + 3
3 + 3
6
-------------------
6(.50) - 2
3 - 2
1
P = 2 (l + w)
P = 2(6 + 1)
P = 2 x 7
P = 14
Answer:
2
Step-by-step explanation:
You can use elimination
x - y = 7
0.5x + y = 5
1.5x = 12
x = 8
Then plug in x into one of the original equations
8 - y = 7
y = 1
Solution is (8,1)
