Answer:

The equation is

y = $ 12.35 x

Step-by-step explanation:

Cost of one bag of rocks = $ 12.35

Let there are x bags of rocks, so that the total cost is y.

So, the cost of 1 bag = $ 12.35

cost of x bags = $12.35 x

The total cost is

y = $12.35 x

It is the equation of a straight line which passes from origin and the slope is 12.35.

Allushta [10]

Answer:

x - 5 = x - 2   and

x - 5 = 2 - x.

Step-by-step explanation:

x - 5 may be positive or negative so we have:

x - 5 = x - 2  

and

x - 5 = - (x  - 2)

x - 5 = 2 - x.

Distribute 
-2(x+6)+3
-2x-12+3
-2x-12+3=-11x+4(x+4)
Distribute 
4(x+4)
4x+16
-2x-12+3=-11x+4x+16
Combine Numbers && Variables 
-2x-9=-7x+16
Add The 7 Over To The -2x 
5x-9=16
Add 9 Over To 16 
5x=25
x=5 
So 5 Is Your Answer

Answer:

16. D. 180 inches

17. A. 1/20 pound

18. D. (2,6)

19. A. 2/8

20. D. 22

Step-by-step explanation:

16. every 5 feet is 60 inches there is 15 feet because 1 yard=3 feet so 60*3=180

17. when you round it upwards you would have 30/40 and 32/40 so it would be 2/40 and then simply 1/20 so therefore it would be 1/20

18. The cost of milk is 3 so that would be (3,y) then every gallon would be y so (3,1)

19. You know this because when you plug in all the other numbers none of the rest of them work but A so therefore it must be A

20. So first you would multiply 2*2*2*2=8 Then you would divide 172/8=22. So therefore your answer would be 22
