Answer:
(0,-8)
x=0
y=-8
Step-by-step explanation:
There are a couple of ways you can solve this I used what I think is called the elimination method
We first start by writing the equations in linear form (y=mx+b)
For the first one we have -12x-5y=40
we add 5y to both sides and subtract 40 to get
-12x-40=5y
divide by 5 to get
-12/5x-8=y
Then the second one we have
12x-11y=88
same deal here, add 11y and subtract 88 to get
12x-88=11y
divide by 11 and get
12/11x-8=y
We then set the two equations equal to each other and get
-12/5x-8=12/11x-8
We can add 8 to both sides and get
-12/5x=12/11x
Just by looking at it you can see that the only solution for x is 0
Plug in 0 to the first equation and get -12*0-5y=40
This means that -5y=40
Solve for y and get -8

Answer:
Andrea has 70
Step-by-step explanation:
7 is the tens place that would make it 70
To answer this you will find the total amount of sunblock that can be filled in 10 hours. Then we will convert the number of ounces to gallons.
1. 150 bottles per hour for 10 hours is 150 x 10.
1500 bottle can be filled.
2. 1500 bottles at 20 ounces per bottle is 1500 x 20
30000 ounces of sunblock
3. There are 128 fluid ounces in each gallon so take 30000 ounces and break it into groups of 128 ounces.
30000/128 = 234.375 gallons
You will need at least 235 gallons of sunblock.
