Step-by-step explanation:
SA = 12(5) + 8(12 + 13 + 5)
Answer:
5, 17
Step-by-step explanation:
For this problem, you need to create a system of equations.
We can name one number x and the other y.
First equation: 2x + 7 = y
Second equation: x + y - 10 = 12, or x + y = 22.
We know y = 2x + 7, so we can substitute that into the second equation.
x + 2x + 7 = 22.
3x = 15
x = 5.
Plug x back into the first equation:
2 · 5 + 7 = y.
y = 10 + 7
y = 17.
Answer:
Actually, you have the correct answer. I think you are confused as to what the exact answer might be.
Answer:
1 hour
Step-by-step explanation:
if he spends 2 hours on his math, then half of that is 1 hour. However, if it's saying that be spend 2 hours on math and english <em>combined</em>, then the answer would only be 30 minutes. Hope this helps (:
So you would use the equation y=mx+b
