Answer:

90 degrees

Step-by-step explanation:

Two angles form a straight line which is 180 degrees.

The two angles are congruent ( or equal to each other )

Let x = measure of one of the angles.

180 = 2x

Divide both sides by 2

180/2 = 90

2x / 2 = x

x = 90

The measure of both angles are 90 degrees

Answer:

It’s 90

Answer:

$879.190 = $879.19

$532.626 = $532.627

Step-by-step explanation:

You round up for the tenths place if the hundredths place is above five, but you round down for the tenths place if the hundredths place is below five. For example, 0 is below five for $879.190, so I round to 9.

Answer:

The chalkboard costs $54.00

Step-by-step explanation:

A chalkboard is in a shape of a rectangle. The chalkboard mentioned measures 1 meter by 2 meters.

The area of a rectangle is given by the formula:

A = lw

Use formula:

A = (2)(1) = 2 m^2

The chalkboard costs $27.00 per square meter so:

2 x 27 = 54

The chalkboard costs $54.00

Step-by-step explanation:

Answer:

M is 4

Step-by-step explanation:

in order to solve, 13=2m+5, you need to subtract 5 from both sides.

13=2m+5

-5        -5

Which is,

8=2m, then you divide both sides by 2. That gives you, 4=m. Therefor, m is 4.

Answer:

x=-7/2, x=4/3

Step-by-step explanation:

[tex]6x^2+13x-28=0[/tex]

Multiply 6 and -28 to get -168

Find 2 numbers that multiply to 168 but add to 13

They are 21 & -8

Rewrite the equation into:

[tex]6x^2+21x-8x-28=0[/tex]

Factor

[tex]3x(2x+7)-4(2x+7)=0[/tex]

(3x-4)(2x+7)=0

3x=4

x=4/3

2x=-7

x=-7/2

Answer:

Step-by-step explanation:

First you want to find the slope

y2-y1/x2-x1

7-(-3)/8-(-3)

Two negatives equal a positive. so Rewrite

7+3/8+3

10/11

Slope=10/11

To find the equation of the line..

y-y1=10/11(x-x1)

y-(-3)=10/11(x-(-3)

Again double negative, so rewrite

y+3=10/11(x+3)

y+3=10/11x+30/11

Subtract three from both sides to isolate 'y'

y+3-3=10/11x+30/11-3

y=10/11x+30/11-3

y=10/11x-3/11

Answer:

40°

Step-by-step explanation:

x+140=180°(angle on a straight line)

x=180-140

x=40°

∠DBA and ∠DBC are making linear pair.

Linear pair of angles are formed when two lines intersect each other at a single point.

Answer:

Martin family: 20 hours

Lewis family: 35 hours

Step-by-step explanation:

Let's say that the Lewis family sprinklers were out for L hours and the Martin family's sprinklers were out for M hours. We know that for each hour that the Lewis family sprinkler was on, 30L of water was put out. We can thus write the Lewis family sprinkler water output as 30L per each hour of L = 30 * L. Similarly, the Martin family sprinkler water output = 15 * M .

We know that the total hours for the sprinklers is 55, so L + M = 55. The total water output for the sprinklers is the sum of the sprinkler outputs, so 30 * L + 15 * M = 1350

L + M = 55

30 * L + 15 * M = 1350

One way to solve this would be to solve for L in the first equation and substitute that into the second

subtract M from both sides in the second equation

55 - M = L

30 * (55-M) + 15 * M = 1350

30 * 55 - 30 * M + 15 * M = 1350

1650 - 15M = 1350

subtract 1650 from both sides to isolate the M and its coefficient

-15M = -300

divide both sides by -15 to isolate M

M = 20

L = 55-20 = 35

Answer:

x=-113

Step-by-step explanation:

2(3x+4)−3(x−1)=x−1x

Step 1: Simplify both sides of the equation.

2(3x+4)−3(x−1)=x−1x

(2)(3x)+(2)(4)+(−3)(x)+(−3)(−1)=x+−1x(Distribute)

6x+8+−3x+3=x+−x

(6x+−3x)+(8+3)=(x+−x)(Combine Like Terms)

3x+11=0

3x+11=0

Step 2: Subtract 11 from both sides.

3x+11−11=0−11

3x=−11

Step 3: Divide both sides by 3.

3x3=−113

x=−113

Answer:

x=−113

Answer:

D

Step-by-step explanation:

A has -1 going to two different y values so it is not a function

B has x = -1 going to two different y values so it is not a function

C has the input of 3 going to two different y values so it is not a function

D each input goes to only 1 output so it is a function

Hey there! I believe the answer would be choice D. because it is the only choice that has one input for each output.

Hope this helps!

Have a wonderful day!

Answer:

74 degrees

Step-by-step explanation:

You can see this is a supplementary angle, which means that it is a straight line with a line sticking out. This means the two angles add up to 180 degrees, so 180 - 106 = 74, which is your answer.

Answer:

x = 74°

Step-by-step explanation:

x + 106 = 180    {linear pair}

Subtract 106 from both sides

        x = 180 - 106

       x = 74°

Answer:

3x^2+4x/16x+8

Step-by-step explanation:

6x²y+8xy/32xy+16y​

Factor the top and bottom

2xy(3x+4)/16y(2x)  -This is the most it can be factored but there is also another way (I'm not sure which one you're looking for)

The problem is that this is not simplified so in order to cancel things out the factored number should be the same.

2y(3x^2+4x)/2y(16x+8)

Cancel out 2y

3x^2+4x/16x+8

Answer:

A.) is my best guess

Step-by-step explanation:

Step-by-step explanation:

Y=

[tex]y = 10 - 8x \\ put \: this \: in \: the \: second \: equation \\ 2(10 - 8x) - 4x = 40 \\ 20 - 16x - 4x = 40 \\ 20 - 20x = 40 \\ - 20 = 20x \\ x = - 1 \\ put \: the \: value \: of \: x \: in \: th \: first \: equation \\ y = 10 - 8( - 1) \\ y = 10 + 8 \\ y = 18[/tex]

Hence, x=-1 and y=18

Answer:

(- 1, 18 )

Step-by-step explanation:

Given the equations

y + 8x = 10 ( subtract 8x from both sides )

y = 10 - 8x → (1)

2y - 4x = 40 → (2)

Substitute y = 10 - 8x into (2)

2(10 - 8x) - 4x = 40 ← distribute and simplify left side

20 - 16x - 4x = 40

20 - 20x = 40 ( subtract 20 from both sides )

- 20x = 20 ( divide both sides by - 20 )

x = - 1

Substitute x = - 1 into (1) for corresponding value of y

y = 10 - 8(- 1) = 10 + 8 = 18

solution is (- 1, 18 )
