Answer: 6/625 gallons of water wa splashed out of the pool
Step-by-step explanation:
Total number of gallons of water in the pool was 10 1/2. Converting to improper fraction, it becomes
21/2 gallons.
Jake and his friend splashed g gallons of water out of the pool. There are 7 7/8 gallons still left in the pool. Converting 7 7/8 to improper fraction, it becomes
63/8 gallons
This means that
g + 63/8 = 21/2
g = 21/2 - 63/8 = (84 - 63)/8
g = 21/8 = 2.625 gallons

Step-by-step explanation:
Carolyn's work is incorrect. Below is the correct solution:
Given:
----› Equation 1
-----› Equation 2
Substitute y = (x + 2) in equation 1
----› Equation 1
(substitution)
(distributive property)
[Note: this is where Carolyn made a mistake]
Collect like terms
(addition property of equality).
Substitute x = 11 in equation 2
-----› Equation 2
(substitution)
✅The solution to the system of equations would be:
(11, 13)
❓❓❓Well think of real life problems?
12x2-7=6-2x2+2
14x^2-15=0
a=14 , b =0 , c=-15
0^2-4x14x(-15) =
