Step-by-step explanation:

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?

Answers

Answer:

Fee - $14.95, and $1.5 per quart of oil

Step-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 = 1.5

Find x by substituting the value of y:

x + 5*1.5 = 22.45x = 22.45 - 7.5x = 14.95

p-1=5p+3p-8

7=7p

p=1

Answer:

p = 1

Step-by-step explanation:

[tex]p-1 = 5p + 3p - 8[/tex]

combine like terms on the right side

[tex]p - 1 = 8p - 8[/tex]

subtract 8p from both sides

[tex]-7p - 1 = -8[/tex]

add 1 to both sides

[tex]-7p = -7[/tex]

divide both sides by -7

graph a line that contains the point (3,-6) and has slope of -1/2​

Answers

Answer:

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Here, m = slope of the line

b = y intercept

Since, m = -[tex]\frac{1}{2}[/tex]

Equation of the line will be,

y = [tex]-\frac{1}{2}x+b[/tex]

Since, a point (3, -6) lies on the line,

-6 = [tex]-\frac{3}{2}+b[/tex]

b = -6 + 1.5

b = -4.5

Equation of the line will be,

[tex]y=-\frac{x}{2}-\frac{9}{2}[/tex]

Table for the points on the graph,

x      -4         -3         -2        -1          0        

y      -2.5      -3       -3.5      -4       -4.5    

Plot these points and join them to get the graph of a line.

There are 60 minutes in an hour, so 8 x 60 = 480 ounces. Then, since we know that there are 128 ounces in a gallon we solve the equation 480 / 128 = 3.75. Now, we know that the pipe would leak 3.75 gallons in an hour. Hope this helped !

The sum of two numbers is 84. The square of the first number is 6 more than the second number

Write a system of equations to find the value of x the first number, and y, the second number.

y = x2 +

Answers

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

The theoretical probability of spinning a 1 is

Answers

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.

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.

Answers

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
