Answer:
x+2y=- 7
x-2y =9
Step-by-step explanation:
Solving Steps
2x+4y=-14
x-2y=9
Divide both sides
(2x+4y) ÷2=-14=2
{x-2y=9
Remove the parentheses
Divide
2x÷2+4y÷2=-7
x-2y =9
Divide
Solution
x+2y=- 7
x-2y =9
I included the formula and the answer
706.5 cubic feet of water should be put in the pool.
Step-by-step explanation:
Given,
The circumference of swimming pool = 157 feet.
The depth of the pool = 6 feet.
For safety purpose
th of its height water is there.
To find the amount of the water should be there.
Formula
The volume of the pool = circumference×height
Now,
The height(h) of the water is = 6×
ft =
ft
So, the volume of the pool = 157×
cubic feet
=
cubic feet = 706.5 cubic feet.
Hence,
706.5 cubic feet of water should be put in the pool.
yes. which questions do you need me to answer?
3x(2 - 5x) - (x - 3)
Simplify.
6x - 15x² - x + 3
Combine like terms.
-15x² + (6x - x) + 3
Simplify.
-15x² + 5x + 3
