What is the value of x?

12

Step-by-step explanation:

Since AC bisects ∠BAD, we know that ∠BAC and ∠CAD are equal to each other. To find x, we set them equal to each other.

9x-54=4x+6                              [subtract both sides by 4x]

5x-54=6                                      [add both sides by 54]

5x=60                                         [divide both sides by 5]

x=12

Now, we know that x is 12.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
