1. The equation c = 2.95g shows how much it costs to buy gas at a gas station on a
Karolina [17]

Answer:

see the procedure

Step-by-step explanation:

we have

c=2.95g

where

c -----> the cost in dollars

g ----> the number gallons of gas purchased

1) For g=1 gal

substitute the value of g in the equation and solve for c

c=2.95(1)

c=\$2.95

The pair (1,2.95) fit the relationship

2) For g=3 gal

substitute the value of g in the equation and solve for c

c=2.95(3)

c=\$8.85

The pair (3,8.85) fit the relationship

3) For g=5 gal

substitute the value of g in the equation and solve for c

c=2.95(5)

c=\$14.75

The pair (5,14.75) fit the relationship

4) For c=$20.65

substitute the value of c in the equation and solve for g

20.65=2.95g

g=20.65/2.95

g=7\ gal

The pair (7,20.65) fit the relationship

Following Quotient expression
IRINA_888 [86]

Answer:

Second choice

and the last 2 choices

Step-by-step explanation:

32m/16m=2 and our constant is 3 not 2 so not choice A

4m^2/2m=2m so possible 6m/2m=3 so choice B

4m/2m=2 and our constant is 3 not 2 so not choice C

10m/5m=2 same reason as A and C

10m^2/5m=2m possible...15m/5m=3 so choice E

32m^2/16m=2m and 48m/16m=3 so this last choice too

A gardener wants to run a border around the outside of her garden. She plots it on a grid to plan how much she will need. The ga
Kamila [148]
Answer: 16 ft

Explanation:

You can determine the lengths of each segment by subtracting the coordinates of the adjacent points.

1) From (2,5) to (8,5): 8 - 2 = 6

2) From (8,5) to (8,3): 5 - 3 = 2

3) From (8,3) to (2,3): 8 - 2 = 6 (as expected as this is congruent to the first

4) From (2,3) to (2,5): 5 - 3 = 2 (as expected as this is congruent to the second).

The total length of the border or perimeter is equal to the sum of all the sides:

perimeter = 6 + 2 + 6 + 2 = 16

Therefore the answer is 16 ft
