Answers

Answer:

12.99x+1.34 is your equation.

Step-by-step explanation:

1.34 is the constant, so take that from the total since it’s not the actual price per CD. 103.92 is the price for all 8 CDs together, so divide that by 8 to get the price per CD.

Write an equation with a slope: -3/4 and y-intercept: -1/4

Answers

Answer:

y = (-3/4)x - 1/4

Step-by-step explanation:

Use the slope-intercept formula y = mx + b.  Here m = -3/4 and b = -1/4, and so:  y = (-3/4)x - 1/4

The equation of the line with slope  -3/4 and y-intercept is -1/4 is y=-3/4x-1/4.

What is slope intercept form of line?

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of the line is the ratio of the rise to the run, or rise divided by the run.

It describes the steepness of line in the coordinate plane.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Given that the slope is -3/4 and y-intercept is -1/4.

We have to find the equation of line with slope -3/4 and y-intercept is -1/4.

m=-3/4 and b = -1/4

Now plug in these values in slope intercept form y=mx+b

y=-3/4x-1/4

Hence, y=-3/4x-1/4 is the equation of the line with slope  -3/4 and y-intercept is -1/4.

Determine whether the measures for the figure shown proportional.

A. the length of a side and the perimeter

B. the length of a side and the area

Answers

Answer: 5 length & width

Step-by-step explanation:

Since this is a square all sides would be the same length & width which would be 5 because each side is symmetric. So if you do 5 times as many sides as there is (5 x 4) it would give you 20

So the LENGTH of EACH side is 5 and the AREA in total or PREMIETER would be 20 all together.

ab - cd = 0
solve for C

Answers

c= ab/d


step by step:
1. isolate the term in C, ab=cd
2. divide both sides by the coefficient of c, which is d
ab/d = cd/d
3. the d’s cancel
ab/d=c
but to make it look nicer, c= ab/d. both answers are correct though!

Answer:

c = ab / d

Step-by-step explanation:

ab − cd = 0

Add -ab to both sides:

ab − cd+− ab= 0 +− ab

−cd=−ab

Divide both sides by -d:

− cd/−d = − ab /−d

c = ab / d

The library loans 4 times as many non-fiction books as it does
fiction books. Write a rule for the relationship between the two
variables. Use n for non-fiction and f for fiction.

Answers

N * 4 =f
We know there are 4 times as many non-fiction books as there are fiction books so we would have to multiply non-fiction by 4 to figure out how many fiction books there are

The rule for the relationship between the nonfiction and fiction books as an expression is n = 4f.

We have,

Let's write a rule for the relationship between the number of non-fiction books (n) and the number of fiction books (f) based on the given information.

We are told that the library loans 4 times as many non-fiction books as it does fiction books.

This means that the number of non-fiction books (n) is equal to 4 times the number of fiction books (f).

Mathematically, we can express this relationship as:

n = 4f

Where:

n = Number of non-fiction books

f = Number of fiction books

Thus,

The rule for the relationship between the nonfiction and fiction books as an expression is n = 4f.

Holland added three decimals that made a sum of 2. One of the decimals was 0.34.

What are two other decimals Holland could have used to make a sum of 2? Explain how you know.

Answers

2 - 0.34 = 1.66

0.96 + 0.7 = 1.66

Holland could have used 0.96 and 0.7 (or any other 2 decimals that add up to 1.66).

The two other numbers could be 0.83.

First, do the equation 2 - 0.34 = 1.66.

Next, divide 1.66 ÷ 2 = 0.83.

Finally, add 0.83 + 0.83 + 0.34 = 2.

So the two other decimals Holland could do is 0.83.

There is only one number that has x, so 5x.

Same with b. 5x + 2b.

Now, there is no letter with the 7, so that will stay the same.

So, the answer is 5x + 2b -7.

supplier C has 10 crates plus five loose pairs

write another expression describing the number of shoes available for each retail store if the shoes are divided equally among stores.

Answers

Answer: 20c + 10.

Step-by-step explanation:

(c represents crates)

I wrote each equation separately first.

Supplier A: 4c + 6

Supplier B: 6c - 1

Supplier C: 10c + 5

We can add all the cs from each supplier giving us 4c + 6c + 10c which equals 20c. Now we can add the extra shoes as, 6 + (-1) + 5 equaling 10. I wrote -1 because we are missing that shoe, but you can write it as 6 - 1 + 5 instead. Together the two numbers make the equation 20c + 10. Hope that helps : )

I got the answer 20c+10

4c+6 for supplier A
6c-1 for supplier B
10c+5 for supplier C

Combining the like terms of C you would get 20c
Then combining the other number (-1,6,5) you get 10

Martin Luther King Jr was 5 feet tall, 7 inches (67 inches) tall. The statue is 30 feet tall. What is the ratio of Martin Luther King Jr's actual height to the statue?

Answers

Answer:

67 inches : 360 inches

Step-by-step explanation:

30 feet = 360 inches

Martin Luther King Jr : Statue

                              67 : 360

                             

The ratio of Martin Luther King Jr's actual height to the statue is 67 : 360.

What is a ratio?

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

Martin Luther King Jr height = 5 feet tall and 7 inches

This is 67 inches tall.

The statue height = 30 feet tall.

This is 12 x 30 = 360 inches

Now,

The ratio of Martin Luther King Jr's actual height to the statue.

= 67 : 360

Thus,

The ratio is 67 : 360.
