Answer:
3g = 30
Step-by-step explanation:
Well, lets check each one to see if any leaves g = 0
12g = 0 (Given)
<em>÷12 ÷12 </em>(Get "g" on its own)
g = 0 (0 ÷ 12 = 0)
We know it is not this one since g = 0
3g = 30 (Given)
<em>÷3 ÷3 </em>(Get "g" on its own)
g = 10 (30 ÷ 3 = 10)
This is our answer since g = 10 in this equation, and not g = 0 we know that this is our equation.
<em>Just in case, I will do the other options just not as in-depth!</em>
<em />
g + 8 = 8
<em> -8 -8</em>
g = 0
9g = 0
<em>÷9 ÷9</em>
g = 0
Hope this Helps! :)

Answer:
Step-by-step explanation:
8x - 2y = 6
-8x + 4y = 12
2y = 18
y = 9
8x - 18 = 6
8x = 24
x = 3
(9, 3)
Answer:
Jenkins: 25 hours Alexanders: 20 hours
Step-by-step explanation:
To solve this problem we need to set up two equations. We know the rates of each sprinkler's output and how much total water was output. We know how many hours the sprinklers were on. We are looking for how long each sprinkler was used.
We can make a represent hours because we know the rate of sprinkler's output is per hour.
25a+40b=1425
a+b=45
Now to solve this system of equations we need to isolate a variable on one equation to plug into the other.
a+b=45
a=45-b
Now we can plug this in for a in the other equation.
25a+40b=1425
25(45-b)+40b=1425
Distribute 25 into the parenthesis.
1125-25b+40b=1425
1125+15b=1425
15b=300
b=20
Now we know that the Alexander family used their sprinklers for 20 hours. We can plug this back into the other equation to find b.
a+b=45
a+20=45
a=25
The Jenkins used the sprinklers for 25 hours, and the Alexanders used them for 20 hours.

Answer:
<h2>No</h2>
Step-by-step explanation:
A function is a relation between sets that associates to every element of a first set exactly one element of the second set.
Each element from the first set is assigned exactly one element from the second set.
It's not a function, because for 0 are assigned two elements 1 and 3.
