The correct answer is X = -5
Answer: 22 minutes
Step-by-step explanation: 500-170 means that he drained 330 gallons of water so 330 divided by 15 gallons a minute so you get 22 so it takes 22 minutes to have 170 gallons left in the pool
Answer:
false
Step-by-step explanation:
We are required to find the cost of each cherry tree and rose bushes.
The cost of each cherry tree, x is $8 and the cost of each rose bushes, y is $12
let
<em>cost of each cherry tree = x</em>
<em>cost of each cherry tree = xcost of each rose bushes = y</em>
The equation:
7x + 11y = 188 (1)
13x + 11y = 236 (2)
Subtract (1) from (2) to eliminate y
13x - 7x = 236 - 188
6x = 48
divide both sides by 6
x = 48 / 6
x = 8
substitute x = 8 into (1)
7x + 11y = 188 (1)
7(8) + 11y = 188
56 + 11y = 188
11y = 188 - 56
11y = 132
divide both sides by 11
y = 132 / 11
y = 12
Therefore, the cost of each cherry tree, x is $8 and the cost of each rose bushes, y is $12

(7^x)^4 is equal to 7^(4x).
7^2 * 7^3 is equal to 7^(2+3) which is equal to 7^5.
7^5 / 7^(3x) is equal to 7^(5 - 3x).
you wind up with 7^(4x) is equal to 7^(5 - 3x)
this is true if and only if 4x = 5 - 3x.
