We used the elimination method to find the ordered pair, (x,y), that represents the situation is (12,39).
Number of invoices = 51
Charge for tree installation = $375
Charge for tree trimming = $54
Total amount in invoices = $6,606
Let x and y represent number of installations and number of trimmings respectively.
Hence,
x + y = 51 ...(1)
375x + 54y = 6606
3 (125x + 18y) = 3*2202
125x + 18y = 2202 ...(2)
Multiplying (1) by 18, we get
18x + 18y = 918 ...(3)
(2) - (3)
107x + 0 = 1284
x = 1284/107 = 12
Hence,
y = 51 - 12 = 39.

Answer:
8
Step-by-step explanation:
First off, we need to recognize that the formula for the volume of a sphere is
.
Then, we can plug in our r values one at a time.
The volume for the sphere with a 6-inch radius is about 904.779.
The volume for the sphere with a 3-inch radius is about 113.097.
To find how much greater the larger sphere is, we simply create a ratio between the two numbers: 
Do the division to find that the volume of the larger sphere is about 8 times the volume of the smaller sphere.
I believe it is 20 since I did 4+4+4+4+4 =20 since each shirt has 4 mixes it could have with the pants. Hope I helped
Answer:


The maximum pounds of cheese that Ariana can buy is 8
Step-by-step explanation:
Let
x ---> the amount of cheese In pounds, that Ariana can buy
we know that
The cost of 3 loaves of bread plus the cost of the cheese must be less than or equal to $50
so
The inequality that represent this situation is


solve for x
subtract 10.08 both sides


divide by 4.99 both sides

Therefore
The maximum pounds of cheese that Ariana can buy is 8
