Answer:
2/5 of a mile
Step-by-step explanation:
The easiest approach is to realise that one hour is 3 times longer than
20 minutes. The longer the time, the more they will pave.
2/5 of a mile, in 20 minutes, how much in 60 minutes?(#)
They will pave 3 times more.
2/15 x 3/1 = 6/15 of a mile
6/15 = 2/5 of a mile
Answer:
(- 9, - 9)
Step-by-step explanation:
Given the 2 equations
3x - 4y = 9 → (1)
- 3x + 2y = 9 → (2)
Adding (1) and (2) will eliminate the term in x
(1) + (2) term by term
(3x - 3x) + (- 4y + 2y) = (9 + 9)
0 - 2y = 18
- 2y = 18 ( divide both sides by - 2 )
y = - 9
Substitute y = - 9 into (1) or (2) and evaluate for x
(1) → 3x + 36 = 9 ( subtract 36 from both sides )
3x = - 27 ( divide both sides by 3 )
x = - 9
Solution is (- 9, - 9)
50 + 3x = 7x + 12
This is because of the exterior angle theorem.
If you would like to simplify (3 * x + 5) + (2 * x - 9) - (4 * x + 3), you can do this using the following steps:
(3 * x + 5) + (2 * x - 9) - (4 * x + 3) = 3 * x + 2 * x - 4 * x + 5 - 9 - 3 = 1 * x - 7 = x - 7
The correct result would be x - 7.
