Answer:

3 hours

Step-by-step explanation:

To find the number of hours the plumber was at the house, we need to solve for x.

22x + 50 = 116

22x = 116 - 50

22x = 66

22x/22 = 66/22

x = 3

<h2>Answer:</h2>

<u>Cost of basketball sneakers with tax</u> = $96.12

<u>Amount of tax</u> = 8% of cost price

= 8/100 × 96.12

<u>Cost of sneakers without tax</u> = $96.12 - $7.6896.

= $88.43.

#19<br> The distance between the points (4, 1) and (9, 1) is
kirill115 [55]

Hello!

Given the two points, (x_{1}, y_{1}) and (x_{2}, y_{2}), and to find the distance between these two points is found by using the formula:

d = \sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}

(x_{1}, y_{1}) is assigned to one the points, in this case, is (4, 1).

(x_{2}, y_{2}) is assigned to other point, which is (9, 1).

Then, plug in these values into the formula and solve.

d = \sqrt{(9-4)^{2}-(1-1)^{2}}

d = \sqrt{5^{2}-0^{2}}

d = \sqrt{25}

d = 5

Therefore, the distance between the two points is 5.
