To find how long it would take, you must divide the total amount of gallons of water in the pond by the amount of gallons drained per hour. This would translate to:
4290 ÷ 78
Which would give you the total amount of hours needed to completely drain the pool, aka the answer:
4290 ÷ 78 = 55
Answer:
x = - 1, y = 2
Step-by-step explanation:
Given the 2 equations
6x + 5y = 4 → (1)
19x + 2y = - 15 → (2)
Multiplying (1) by 2 and (2) by - 5 and adding will eliminate the term in y
12x + 10y = 8 → (3)
- 95x - 10y = 75 → (4)
Add (3) and (4) term by term thus eliminating y
- 83x = 83 ( divide both sides by - 83 )
x = - 1
Substitute x = - 1 into either of the 2 equations and evaluate for y
Substituting into (1)
6(- 1) + 5y = 4
- 6 + 5y = 4 ( add 6 to both sides )
5y = 10 ( divide both sides by 5 )
y = 2
Answer:
y + 10 = 0
Step-by-step explanation:
Slope of horizontal line is zero (0)
m = 0
By point slope form of a line.
74.75÷5≈15. As a result, the unit rate is about 15. Hope it help!
Width-24 Length-29
Two sides of the rectangle are 5 cm bigger than the other two. So you would add the two 5 cm together (10cm). If you take the 10 cm off you (106-10) you will get a square. Then all you have to do is divide 96 by 4 (24), and add back on the two 5cm from the beginning to the length (29).
