Answer:

The equation is C, and the correct answer is 6 (D)

Step-by-step explanation:

We first look for the correct equation. If Matt charges 9 dollars per hour, and earned a total of 99, then we known that 9*the number of hours = 99. Moving on, we know that he babysat Friday night for 5 hours, but we don't know the number on Saturday. BUT we do know that 5+saturday hours = total number of hours. Putting this into a formula, we get 9(5+x (where x = #of hours worked on saturday) = 99(total number)

Our final equation is 9(5+x)=99.

Solving this by dividing both sides by 9, we get 5+x=11. Subtracting 5 from both sides gives us x = 6.

azamat

Length = 2*width - 5
perimeter = 2(length + width)
89 = 2(2width - 5 + width)
89 = 6 width - 10
6 width = 99
width = 99/6 = 16.5 feet

Answer:

The angle between the two sides of the right triangle is aproximately 31.003º.

Step-by-step explanation:

From image attached on question we infer that we need to find the angle between sides of lengths 6 (adjacent leg) and 7 (hypotenuse) in the right triangle. The angle can be found by means of this trigonometric ratio:

$\cos \alpha = \frac{6}{7}$
