5.Mitch has 35 more bouncy balls than Rudy. Rudy has b bouncy balls. Choose the expression that shows how many bouncy balls Mitch has. *

6. A pizza delivery driver earns $8 an hour and works h hours per day. He also spends $20 a day on gas. How much will the driver earn in one day?

1. 7r

Its simple 7 times r = the number of chairs.

2. g - 29

Kenneth has 29 more than maggie or maggie has 29 fewer because we are finding out how many maggie has you have to subtract so g - 29

3. 40m + 35

For this question  We have the variable M which is used for months you get charged 40$ a month with a one time activation fee. leaving only option C. as the correct answer.

4. 5m

The reason here, is there are 5 total people helping. m represents money therefore it must be 5m.

5. b +35

This is just simply reading the question. You are trying to find the amount mitch will have meaning the given variable and number are all you need. So given that the answer will be b + 35.

6. 8h - 20

This will be the equation which you need. you are given all the information needed without doing work. First look at hours. He is paid $8 an hour. He works an unknown amount of hours a day so 8h. Finally he is subtracted $20 for gas leaving you with the equation 8h - 20.

Have a great day all.

36 is the final answer! : )

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
