A dozen apples cost $3. At this rate how much will 7 apples cost?

Answer: hey

Step-by-step explanation:

Answer:

y=25x-5

Step-by-step explanation:

y=mx+b

the 25=m and the constant would be 5. However its a negative five because your losing -5 every hour.

Make me brainliest pls

Answer:

y=25x-5

Step-by-step explanation:

Answer:

X = 45

Step-by-step explanation:

Answer:

m∠A = 45 degrees

m∠B = 110 degrees

m∠C= 25 degrees

Step-by-step explanation:

In a triangle, all interior angles add up to 180, which means:

x + x+65 + 25 = 180

2x + 90 = 180

2x = 90

x = 45

m∠A = 45

m∠B = (45+65) = 110

m∠C= 25

Answer:

46

Step-by-step explanation:

Answer:

A and D are functions

Step-by-step explanation:

A is a function because each output is going down the same amount each time, in this case, going down by 4. (the function here is y = -x + 11)

B is not a function because there isn't a constant for y.

C isn't a function either because two x's are 0 with different y values, and you can't have that in a function.

D is also a function because of the equation on the right side.

The red line of the attachment below in A's function graphed, and the lime curve represents D's function graphed.

Answer:

80 racquets per hour.

Step-by-step explanation:

Divide 240 by 3, and you'll get 80.  To double check, divide 400 by 5 and you'll still get 80.  Hope that helps.

Answer:

Last moth I spent $45 on clothing.

Step-by-step explanation:

To solve this problem, we just need to find 150% of $30.

30 x 1.50 = 45

Therefore, last moth I spent $45 on clothing.

Hope this helps! :D

Answer:

Jane is 52 7/40 inches tall

Step-by-step explanation:

What you do is you subtract 1 3/8 from 54 3/4 which gives you Carl's height, which is 53 3/8.

Lastly, you subtract 1 1/5 from 53 3/8 which is 52 7/40.

Answer: 52 7/40

Step-by-step explanation:

Answer:

Answer:

Step-by-step explanation:

Take original price divide by one hundred multiply that by percentage, subtract what you get from original price and that’s your sale price

Answer:

let's say the price is 400 dollars

and the percent of markdown is 20%

100-20=80

400x80=32000

32000/100= 320

The price will be 320 dollars.

Answer:

[tex]y=2x+4[/tex]

Step-by-step explanation:

You can solve this two ways: insert the values into point-slope form and simplify to solve for y, converting it to slope-intercept form, or insert the values into slope-intercept form, solve for b, and insert b. We'll do both :)

Point-slope form:

[tex]y-y_{1}=m(x-x_{1})[/tex]

Where:

Insert the given values:

[tex]m=2\\\\(-5_{x_{1}},-6_{y_{1}})\\\\y-(-6)=2(x-(-5))\\\\y+6=2(x+5)[/tex]

Solve for y. Expand the right sie using the distributive property:

[tex]y+6=2(x)+2(5)\\\\y+6=2x+10[/tex]

Isolate the variable. Subtract 6 from both sides, canceling out the 6 on the left:

[tex]y+6-6=2x+10-6\\\\y=2x+4[/tex]

OR

Slope-intercept form:

[tex]y=mx+b[/tex]

Where:

Insert the given values:

[tex]m=2\\\\(-5_{x},-6_{y})\\\\-6=2(-5)+b[/tex]

Simplify the multiplication:

[tex]-6=-10+b[/tex]

Solve for b. Add 10 to both sides, canceling out the 10 on the right:

[tex]-6+10=-10+10+b\\\\4=b[/tex]

The value of b is 4. Insert the appropriate information into the equation. When using slope-intercept form, you don't plug in the coordinate points:

[tex]y=2x+4[/tex]

:Done

Answer:

1 x 12

3 x 4

2 x 6

Step-by-step explanation:

multiply them and you get 12 voila

Answer:

1 x 12

3 x 4

2 x 6

Step-by-step explanation:

16c - 7 = 13.32

16c = 13.32 + 7

16c = 20.32

c = 20.32/16

c = 1.27

Answer:

20/20: D

Step-by-step explanation:

First turn both the fractions into twentieths.

3/5 = 12/20

8/20

Then add 12/20+8/20=20/20

20/20 = 1

Answer:

x = 5

Step-by-step explanation:

To solve for x in 5x - 2 = 3x + 8 start by getting the variables on the same side. To do this, subtract 3x from 5x. (you always do the opposite of the term's operation)

2x - 2 = 8 now add 2 to 8

2x = 10 now divide 2

x = 5

I hope this helped :)
