A bowling alley charges each person $6 to play a game and $4.50 to rent a pair of bowling shoes. Write an expression to show how much the bowling alley will charge f friends if they each play 3 games and all but one of them rents shoes.

Answers

Write an expression to show how much the bowling alley

cost = f($6 x 3) + (f - 1) x $4.50

c=9f+4.5*(f-1)

Final answer:

The expression to calculate the total cost for f friends playing 3 games each, with all but one renting shoes, is 6 * 3 * (f - 1) + 4.50 * (f - 1).

Explanation:

To calculate the total cost for f friends playing 3 games each, all but one renting shoes, we can write the expression: 6 * 3 * (f - 1) + 4.50 * (f - 1). The cost of each game is $6, and since each person plays 3 games, we multiply that by 3. The cost of renting shoes is $4.50, and since all but one person rents shoes, we multiply that by (f - 1).

Solve x: 3x-7 = 5x+13
Solve x: 7-3x = 5x+13

Answers

first you need to combine like terms
7-3x= 5x+13
step 1 add 3x
7=8x+13
step 2 subteact 13
-6=8x
step 3 divide both sides by two
x=-3/4

1.
Since 5x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 5x from both sides.
3x−7−5x=13

Add 3x and −5x to get −2x.
−2x−7=13

Move -7 to the right hand side of the equation.
−2x=7+13

Add 7 and 13 to get 20.
−2x=20

Divide each term in the equation by −2.

x=−10

2.
Since 5x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 5x from both sides.
7−3x−5x=13

Add −3x and −5x to get −8x.
7−8x=13

Move 7 to the right hand side of the equation.
−8x=−7+13

Add −7 and 13 to get 6.
−8x=6

Divide each term in the equation by −8.

x=−3/4

Stuart is buying a pair of jeans that regularly cost $40. They are on sale for 20% off. If the tax rate is 8%, what is the sale price of the jeans including tax?a. $21.60
b. $34.56
c. $42.34
d. $44.16

Answers

well first you want to add the sales tax which would be 8% of 40 which is 3.2. So it costs $43.2 without the discount. so then you want to find 20% of 43.2 which is 8.64. So the last step is to subtract 8.64 from 43.2 which is

43.2 - 8.64 = $34.56 is your answer

please mark brainliest if this helped

40$ x .20 or 20% = 8
40$ + 8 = 32$
32$ x .08 or 8% = 2.56 the tax rate
32$ + 2.56 = 34.56$ Price of jeans including tax.
