Answer:
4.5 hours
Step-by-step explanation:
let t be the time elapsed
Therefore, we can set up a system of equations and solve accordingly
2t + 16.5 = 4t + 7.5
2t = 9
t = 4.5 hours more till they paint the same amount in square feet
If 15 mm is a side from the original and 6 mm is the same side from the newly dilated figure, then the scale factor is:
6/15
Simplify:
2/5 or 0.4
Answer:
Step-by-step explanation:
Multiply the first by -2
Multiply the second by 3
so the x variable can be cancelled,eliminated
3x +2y =17
2x+5y = 26
-6x - 4y = -34
6x +15y = 78
11y = 44
y=4
Now plug this value to get x
3x+8 = 17
3x = 9
x=3
The answer (3,4)
