A service center charges a fee of x dollars for an oil change plus y dollars per quart of oil used. A sample of its sales record is shown.
A table shows the oil tank size in quarts and total cost for two customers. Customer A: Oil tank size, 5 quarts. Total cost, 22.45 dollars. Customer B: Oil tank size, 7 quarts. Total cost, 25.45 dollars.
Write a system of linear equations that represents this situation.
Equation for customer A:
____=22.45$
Equation for customer B:
___=25.45$
Question 2
Find the fee and cost per quart of oil.
$ fee?
$ per quart of oil?
Answer:
Fee - $14.95, and $1.5 per quart of oilStep-by-step explanation:
Equation for customer A:
x + 5y =22.45$Equation for customer B:
x + 7y=25.45$Subtract the first equation from the second and solve for y:
x + 7y - x - 5y = 25.45 - 22.452y = 3y = 3/2y = 1.5Find x by substituting the value of y:
x + 5*1.5 = 22.45x = 22.45 - 7.5x = 14.95solve for x using the correct order operations
12- (3 times 2)^2 + 4 times 3 = x
A x = -60
B x = -12
C x= 48
D x = 12

Error Analysis
identify the first step that contains an error.
Solve: -38 = 4x -2(x + 5)
Step 1: -38 = 4x - 2x -10
Step 2: -38 = 2x - 10
Step 3: -48 = 2x
Step 4: -24 = x
Answer:
Step-by-step explanation:
-38 = 2x - 10 becomes -28 = 2x, NOT -48 = 2x.

The theoretical probability of spinning a 1 is
Answer:
Step-by-step explanation:
That depends on how many sections there are. If there are 2 sections, then it will be a 50/50 chance it lands on 1 if there are 3 sections then it would be 1/3 or for 4, 1/4, and for 5, 1/5, etc.
The theoretical probability of spinning a 1 is 1/4.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Theoretical probability is the probability that we find through the theoretical approach without doing the experiment.
Total number of sections that the spinner has = 4
Number of sections numbered 1 = 1
Probability of spinning a 1 = 1/4
Hence the required probability = 1/4.

1. A rectangular garden has a perimeter of
120 feet. The length of the garden is 24 feet
greater than twice the width. The system of
linear equations 21 +2w = 120 and 1-2w = 24
represents this situation, where I is the
length of the garden and wis the width. Find
the length and width of the garden.
Answer:
Length: 48
Width: 12
Step-by-step explanation:
Substition
l - 2w = 24
I = 60 - w
60 - w - 2w = 24
60 - 3w = 24
-3w = -36
w = 12
Substitute it into the equation to get the length.
l = 60 - 12
l = 48
the graph of y=f(x) is shown. a. estimate the turning point of the graph
Answer:
a) The location of the turning point is approximately [tex]V(x,y) = (-0.25, -2,1)[/tex].
b) Roots are approximately [tex]x_{1} \approx -1.3[/tex] and [tex]x_{2} \approx 0.8[/tex].
c) [tex]f(1.5) \approx 4[/tex]
Step-by-step explanation:
a) The figure presents the graphic of a parabola, that is, a second order polynomial, with an absolute minimum (vertex). The turning point of the graphic, that is, the point in which behavior of the curve changes, is the vertex. Hence, the location of the turning point is approximately [tex]V(x,y) = (-0.25, -2,1)[/tex]
b) According to the Quadratic Formula, second-order polynomials can have either two real roots or two conjugated complex roots. In this case, we have two real roots. A root corresponds with the point of the curve that passes through x-axis. In this case, roots are approximately [tex]x_{1} \approx -1.3[/tex] and [tex]x_{2} \approx 0.8[/tex].
c) [tex]f(1.5)[/tex] is the function evaluated at [tex]x = 1.5[/tex], that is, the value on y-axis associated with [tex]x = 1.5[/tex]. Lastly, we conclude that [tex]f(1.5) \approx 4[/tex].

Does anyone know how to do simple interest for 7th grade math? I need a tutorial or an example please, thanks. A question example is $750, 7%, 3 years.
Answer:
750/100 X 7 = 52.50
52.50 X 3 = $157.50
Step-by-step explanation:
divide principal amount by 100 then multiply by interest percentage. this gave 52.50
now multiply the interest amount by number of years
in this case 3
52.50 X 3 = $157.50

(the rectangular room measures 224 square feet. One side of the room is 14 feet long. what is the perimeter os the room?
Answer:
The perimeter of the room is 60 feet.
Step-by-step explanation:
If the area of the room is 224 square feet, and one side is 14 feet, then the other side is 224/14 feet, or 16 feet.
This gives us the dimensions of the room, 14 x 16.
From this, we can calculate the perimeter, which would be 2(14+16), or 60.

Write a system of equations to find the value of x the first number, and y, the second number.
y = x2 +
Answer:
[tex]x + y = 84[/tex]
[tex]x^2 = 6 + y[/tex]
Step-by-step explanation:
Given
x = First Number
y = Second Number
Required
Write a system of equations
Sum is 84
This is represented as:
[tex]x + y = 84[/tex]
Square of first is 6 more than the second
This is represented as:
[tex]x^2 = 6 + y[/tex]
Hence, the equations are:
[tex]x + y = 84[/tex]
[tex]x^2 = 6 + y[/tex]
Answer: for plato users
y = -x+ 84
y= x^2 + -6
