Do you know how to use elimination method?
2x+10 x + 3
------------ = --------------
10 4
4(2x+10) = 10(x+3)
8x + 40 = 10x + 30
2x = 10
x = 5
AE =2x+10 = 2(5) +10 = 20
answer
20 units
<span>You paint 1313 of a wall in 1414 hour.
Now we need to find the rate in order you to paint one wall.
1313 : 1414 = 1 : X
1414 = 1313 X
X = 1.08
So the rate per one wall is 1.08 hours.</span>
Answer:
A. x + y = 34; 10x + 15y = 410
Step-by-step explanation:
Jody's total hours will be the sum of the hours spent on each job:
x + y = 34 . . . . . total hours
Jody's total earnings will be the sum of the earnings from each job:
10x +15y = 410 . . . total earnings
So, the system of equations is ...
- x + y = 34
- 10x + 15y = 410
Answer:
20 + 2 units
