The angle should be 74 degrees and they are supplementary

Step-by-step explanation:

It is 74 degrees because the two angles must add up to 180, so you can simply subtract 106 from 180 to get 74. The angles are supplementary because they add up to 180 degrees, while complementary angles only add up to 90 degrees

−112.74 = 9.2p − 9.7

Answers

Answer:

p= -11.2

Step-by-step explanation:

-112.74 = 9.2p - 9.7

-103.04 = 9.2p (added 9.7 to both sides because its the inverse operation)

[tex]\frac{-103.04}{9.2}[/tex] = [tex]\frac{9.2p}{9.2}[/tex]

-11.2 = p

Leah is writing an equivalent equation which solves for y. What should be her next step? 3 x + 4 y = 8. 3 x minus 3 x + 4 y = 8 minus 3 x. 4 y = 8 minus 3 x.

Answers

Given :

A linear equations :

3x+4y = 8 .

She have completed the following steps :

3x+4y = 8

3x+4y-3x = 8-3x

4y = 8 -3x

To Find :

The equivalent equation which solves for y.

Solution :

General equation of line or equation which solves for y is given by :

y = mx +c

So , our next step should be dividing both sides by 4 .

[tex]\dfrac{4y}{4}=\dfrac{8}{4}-\dfrac{3x}{4}\\\\y=2-\dfrac{3x}{4}[/tex]

Therefore , equation which solves for y is [tex]y=2-\dfrac{3x}{4}[/tex] .

Hence , this is the required solution .

I am in 8th and I thinks it’s 2

Answer:

see explanation

Step-by-step explanation:

Since B is the midpoint of AC, then

AB = BC , substitute values

3x - 5 = x + 5 ( subtract x from both sides )

2x - 5 - 5 ( add 5 to both sides )

2x = 10 ( divide both sides by 2 )

x = 5

Thus

BC = x + 5 = 5 + 5 = 10

What is 360 divided by 11.

Answers

32.7272727 hope that help
Step 1:
Start by setting it up with the divisor 11 on the left side and the dividend 360 on the right side like this:

1 1 ⟌ 3 6 0

Step 2:
The divisor (11) goes into the first digit of the dividend (3), 0 time(s). Therefore, put 0 on top:

0
1 1 ⟌ 3 6 0

Step 3:
Multiply the divisor by the result in the previous step (11 x 0 = 0) and write that answer below the dividend.

0
1 1 ⟌ 3 6 0
0

Step 4:
Subtract the result in the previous step from the first digit of the dividend (3 - 0 = 3) and write the answer below.

0
1 1 ⟌ 3 6 0
- 0
3

Step 5:
Move down the 2nd digit of the dividend (6) like this:

0
1 1 ⟌ 3 6 0
- 0
3 6

Step 6:
The divisor (11) goes into the bottom number (36), 3 time(s). Therefore, put 3 on top:

0 3
1 1 ⟌ 3 6 0
- 0
3 6

Step 7:
Multiply the divisor by the result in the previous step (11 x 3 = 33) and write that answer at the bottom:

0 3
1 1 ⟌ 3 6 0
- 0
3 6
3 3

Step 8:
Subtract the result in the previous step from the number written above it. (36 - 33 = 3) and write the answer at the bottom.

0 3
1 1 ⟌ 3 6 0
- 0
3 6
- 3 3
3

Step 9:
Move down the last digit of the dividend (0) like this:

0 3
1 1 ⟌ 3 6 0
- 0
3 6
- 3 3
3 0

Step 10:
The divisor (11) goes into the bottom number (30), 2 time(s). Therefore put 2 on top:

0 3 2
1 1 ⟌ 3 6 0
- 0
3 6
- 3 3
3 0

Step 11:
Multiply the divisor by the result in the previous step (11 x 2 = 22) and write the answer at the bottom:

0 3 2
1 1 ⟌ 3 6 0
- 0
3 6
- 3 3
3 0
2 2

Step 12:
Subtract the result in the previous step from the number written above it. (30 - 22 = 8) and write the answer at the bottom.

1. For the equation, x-7 = 24. can a value be substituted for x to make that a true
number sentence? How many values could be substituted for x and have a true
number sentence?

Answers

Answer:

The value 31 can be substituted for x. Only the value 31 can be substituted.

Step-by-step explanation:

So to solve a one step equation the goal is to isolate the variable. As you can tell from we are subtracting the 7. The opposite of addition is subtraction so we want to add the 7. -7 plus a positive 7 is 0 which cancels it out. Now we have x=24. However what you do to one side you need to do to the other. So we add 7 to the 24. 7+24 is 31. Therefore 31 can be substituted for x. Lets check out answer. What is 31-7? 31-7 is 24. Now we know our work was correct

Write the following equations in slope intercept form
Equation 1: y-7x=6
Equation 2: y+7x=8

Answers

Answer:

Equation 1: y = 7x + 6

Equation 2: y = -7x + 8

Step-by-step explanation:

Isolate the y variables in both equations

Equation 1:

y - 7x = 6

y = 7x + 6

Equation 2:

y + 7x = 8

y = -7x + 8

So, the equations in slope intercept form are:

Equation 1: y = 7x + 6

Equation 2: y = -7x + 8
