Answer:

B) 57

Step-by-step explanation:

since BD ≅ BC then ∡C = ∡D

6x-9 = 3x + 24

subtract 3x from each side to get:

3x-9 = 24

add 9 to each side to get:

3x = 33

divide each side by 3 to get:

x = 11

substitute 11 into 'x' in 3x + 24 to get:

3(11) + 24 = 33+24 = 57

check:

substitute 11 into 'x' in 6x - 9 to get:

6(11) - 9 = 66 - 9 = 57

The graph below shows the cost of bag tags based on the number of bag tags ordered:

Ksenya-84 [330]

Hi there.

We know that the cost of 2 bags is $4, which can be modeled as 2n.

All we need to do is replace the variable with the number of bags.

$2 \times 1 = 2$
The cost of 1 bag is $2.

Hope this was correct, lol.
