Part A: Rhett made $250 washing cars with his mobile car wash company. He charges $70 per car and earned $50 in tips. Write an equation to represent this situation. (4 points)
Part B: Scarlett made a profit of $250.00 with her mobile car wash company. She charged $75.00 per car wash and received $35.00 in tips, but also had to pay $5.00 in cleaning supplies per car wash. Write an equation to represent this situation. (4 points)
Part C: Explain how the equations from Part A and Part B differ. (2 points)
Answer:
Part A 70x+50=250
Part B(75x + 35) = 250 - 5x
Step-by-step explanation:
Here to form an equation you must add all the money that she earned and subtract the money that she had to spend We dont know how many car washes she did, so we must represent it with a variable, or x.
Answer:
Step-by-step explanation:
Part A: Rhett washed 3 cars and earned $50 in tips. y=70x+50
Part B: $75 - $5 = $70 (this is the amount charged minus the amount needed to get the job done per car wash)
the +35 is the tips extra/ constant that will be added after the jobs are done.
x is the number of car washes done
y would be the profit received.
so y = 70x + 35 (profit = value of car wash * number of cars washed + tips)

how to make h the subject in
m= r - h + 4d
9514 1404 393
Answer:
h = r +4d -m
Step-by-step explanation:
There are a couple of ways to go about this:
1) Solve it the way you would any 2-step linear equation.
Step 1:
Identify the terms that do not involve h on the side of the equation that has the h-term. Subtract those terms from both sides of the equation.
m -r -4d = -h
Step 2:
If the coefficient of h is not 1, divide both sides of the equation by that coefficient.
(m -r -4d)/(-1) = (-h)/(-1)
-m +r +4d = h
I like to have the leading coefficient be positive, so I might write this as ...
h = 4d +r -m
__
2) The only h term has a -1 coefficient, so it can be given a coefficient of +1 by adding h to both sides of the equation.
h +m = r +4d
There is an unwanted m term with the h term, so subtract that from both sides of the equation.
h = r +4d -m
Answer:
h = 4d -m + r
Step-by-step explanation:
m = r-h +4d
h = 4d -m + r
we know when the real root is r = h-4d
the m+h = r+4d is step 1
then simply h-m = 4d-m + r is step 2
then h = 4d -m + r
The area of a fenced in back yard can be 144 square feet. The owners are trying to decide on the dimensions of the back yard, and have decided they want the length to be 10 feet more than its width. What will the dimensions of the back yard be?
A rectangle can be defined as a 4 sided geometric figure. One side of a rectangle is longer than the other sides. A rectangle can also be referred to as a quadrilateral.
The dimensions of the background are given as Width: 8 feet and the Length: 18 feet
The formula for the area of a rectangle is Length x Width.
The question says:
The owners want the length to be 10 feet more than its width. Hence:
L = W + 10
The area of the fenced backyard = 144 square feet.
Hence,
(W + 10) x W = 144
W² + 10W = 144
Rewriting the equation
W² + 10W - 144 = 0
We factorize the algebraic expression above
W² - 8W + 18W - 144 = 0
W(W - 8) + 18(W - 8) = 0
(W - 8) (W + 18) = 0
W - 8 = 0, W = 8
W + 18 = 0, W = -18
Since the width cannot be a negative value, the width of the backyard is 8 feet
Solving for the Length,
L = W + 10
L = 8 + 10
L = 18 feet
The length of the backyard is 18 feet.
Therefore, the dimensions of the backyard are Width: 8 feet and Length: 18 feet.

Estelle is having her birthday party at Gold Frames Art Museum this year. A party package costs $265 and covers the entrance fee for guests, a private party room, and an activity guide. Estelle upgraded her package to include a favor for each of her 8 guests, bringing the total to $305.
Using proportions, it is found that the cost of each of the favors is of $5.
Proportions:This question is solved by proportions, using a rule of three.The addition of 8 favors increase the cost of the party by $40. What is the cost of one favor?The rule of three is:
8 favors - $40
1 favor - $x
Applying cross multiplication:
[tex]8x = 40[/tex]
[tex]x = \frac{40}{8}[/tex]
[tex]x = 5[/tex]
The cost of each of the favors is of $5.
