Answer

Step-by-step explanation:

First, you have 12+n=15

Second, solve for n

Answer:8 times 4+12+= 44

Step-by-step explanation:

8 times 4 gives you 32 then add 12 to get 44

Answer:

Slope: -1

x-intercept: (-7, 0)

y-intercept: (0, -7)

Explanation:

y

=

−

x

−

7

Step-by-step explanation:

I DONT KNOW  I JUST HAVE DONE THIS LOL

slope intercept form is y = mx + b.

the m represents slope and the b represents the y-intercept.

therefore, the answer to your problem would be:  y = -1/7x - 8/7

Answer:

C

Step-by-step explanation:

add 8 + 8 + 4 + 4 = 24 ft

so maybe it is C

Answer: An equation that you can use is 4(7.5)

Step-by-step explanation:

Formula for perimeter is P=4a, so it would be P=4(7.5) which equals 30

I really hope this helps!

Answer: 130.4

Step-by-step explanation:

find the area of the rectangles

5(8)=40

5(8)=40

4(8)=32

find the area of both of the triangles

formula: 2(bh÷2)

substitute: 2(4 x 4.6 ÷ 2)

solve

2(9.2)

18.4

add all of the areas

40+40+32+18.4=130.4

Answer: x is less then 5 over 4. Open circle on 1.25 shading to the left on the number line.

Step-by-step explanation:

Step 1: 16x is less than 20

step 2: divide by 16, 16x over 16 is less than 20 over 16.

step 3:  x is less than 5 over four (1.25)

Answer:

The angles are complementary; X = 15

Step-by-step explanation:

When angles are complementary, they always add up to 90 degrees angles, which is a right angle. Supplementary angles add up to 180 degree angles, which is a straight line. When telling the difference, my math teacher taught me to remember the saying "complementing is always the right thing to do" (it's corny, I know, but it worked for me lol)

To find x, you would do 90 minus the other angle, which is 45, to get 45. Then, you would divide by 3, to get 15 as x.

Answer:

72

Step-by-step explanation:

18 + 18 + 6 + 6 + 12 + 12

Answer:

108[tex]cm^{2}[/tex]

Step-by-step explanation:

Area of parallelogram = bh (base x height)

                                     = 18 x 6

                                     = 108[tex]cm^{2}[/tex]

hope this helps :)

Answer: 13. 180, 14. 192

Step-by-step explanation:

13.

What is the relationship of 5 and 20?

4x5 is 20.

That means y is 4 times more than x.

So, if you apply this to x= 45, what is y?

45x4 =180

This can be used as a ratio

5:20

45: ?

To get 5 to 45, multiply by 9

That means you have to equal out the equation by multiply 20 by 9, = 180.

14.

8: 48

32: ?

8x4 is 32

48x4=192

y= 192

Answer:

v=113.1 m^3

Step-by-step explanation:

v=4/3pi(r)^3

4/3pi(3)^3

v=113.09734m^3

Answer:

y=2x-46

Step-by-step explanation:

Select any two coordinate points. I'm picking (1,-44) and (2, -42).

x1 and y1 are the first coordinates. x2 and y2 are the second coordinates. The formula for finding the slope of a linear fuction is (y2-y1)/(x2-x1). Substiute the numbers into this formula:

-42-(-44)/2-1

=-42+44/1

=2

This is the slope. In y=mx+b, plug in your newly found slope. Next, to find the y-intercept, plug any pair of coordinate points into your incomplete formula y=2x+b. I'm going to use (1,-44) again.

-44=2(1)+b

-44=2+b

b=-46

Now, plug this into your formula, and you'll get y=2x-46.
