Given the figure below, find the values of x and z.

 z = 107; x = 5

Step-by-step explanation:

z = 107   They are vertically opposite angles, which they are equal.

z + (6x + 43) = 180

1. Plug in 107 for z.

107 + (6x + 43) = 180

2. Get rid of parentheses.

107 + 6x + 43 = 180

3. Sum up the number in the left sides.

      6x + 150 = 180

4. Subtract 150 from both sides.

                6x = 30

5. Divided 6 from both sides.

                  x = 5

$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)
