Answer:

A. $ 46

B. 12 people.

Step-by-step explanation:

From the question given above, we obtained the following:

C(x) = 6.5x + 20

Where:

C => total cost of bowling

x => number of people

A. Determination of the of bowling for 4 people.

Number of people (x) = 4

Total cost (C) of bowling =?

C(x) = 6.5x + 20

C(4) = 6.5(4) + 20

C(4) = 26 + 20

C(4) = $ 46

Thus, it will cost $ 46 for 4 people to bowl

B. Determination of the number of people that can bowl for $ 98.

Total cost (C) of bowling = $ 98

Number of people (x) =?

C(x) = 6.5x + 20

98 = 6.5x + 20

Collect like terms

98 – 20 = 6.5x

78 = 6.5x

Divide both side by 6.5

x = 78 / 6.5

x = 12

Thus, 12 people can bowl for $ 98.

Firdavs [7]

Answer:

<h2>Pete played 1.5 times the number of matches that Jack played.</h2><h2 />

Step-by-step explanation:

<u>Pete played 18 tennis matches in a week.</u>

P = 18

<u>Jack played 6 fewer matches than Pete. </u>

J = P - 6

J = 18 - 6

J = 12

<u>How many times the number of matches pete played is the number of matches jack played?</u>

<u />

18 / 12 = 1.5

Pete played 1.5 times the number of matches that Jack played.

How would I do this with working ?

You Just want to get Fahrenheit alone on one side of the equal sign. Your  teacher forgot to use parenthesis. The correct equation for Celsius to Fahrenheit is: C= \frac{5}{9} (F-32)

Which will give you a completely different answer.... F = \frac{9}{5} C + 32

****

We will solve it using what is given:

C = (5/9)F - 32

C + 32 = (5/9)F

9(C + 32) = 5F

(9/5)(C + 32) = F

** If they mark you wrong, and try to say the answer is F = (9/5)C + 32 then they shouldn't be teaching math, and you should point out the fact there are no parenthesis around the F - 32 in the given formula.
