Answer:

2x+3x-15=180°

Step-by-step explanation:

When two angles are supplementary, their angles would equal to 180° total when added together. In this answer, the two angles are added together to create 180°.

Answer:

The answer is D

Step-by-step explanation:

Supplementary angles add up to be 180 degrees, so you put the two angles together equal to that

Answer:

C. The function shown on the graph has a greater rate of change, but a lower starting point.

Step-by-step explanation

5x-6=y (equation on the graph)

4x+2=y

5 is a greater rate of change (slope) compare to 4, however the y-intercept on the graph is lower (starting point) compare to the equation (2)

Answer:

Surface Area= 498 cm²

Step-by-step explanation:

To calculate the surface area of this composite shape, work out the area of each face and add them together (break this composite figure into two shapes)

- Calculate the areas of the different sized faces

7 x 7 = 49

12 x 7 = 84

12 x 7 = 84

- Now, multiply these areas be number of corresponding faces

49 x 2 = 98

84 x 2 = 168

84 x 2 = 168

- Add these areas together

98 + 168 + 168 = 434

Now do the same for the shape above it

2 x 2 = 4  →  4 x 2 = 8

2 x 7 = 14 → 14 x 2 = 28

7 x 2 = 14 → 14 x 2 = 28  = 64

Add the surface areas together : 434 + 64 = 498 cm²

Answer:

  (A) In step 1, the slope of the line should be One-half

Step-by-step explanation:

Terri calculated the slope as (x1 -x2)/(y1 -y2). Her first error was using this formula, when she should have used ...

  m = (y1 -y2)/(x1 -x2)

  = (6 -3)/(4 -(-2)) = 3/6 = 1/2

The best of the offered descriptions is ...

  In step 1, the slope of the line should be One-half

Answer:

y = (1/2)x + 4

Step-by-step explanation:

As we move from the point (-2, 3) to the point (4, 6), x (the 'run') increases by 6    and y (the 'rise')increases by 3.  Therefore the slope of the line connecting the two points is m = rise / run = 3/6, or m = 1/2.

We want the slope-intercept form of the equation of this line.   The basic form is y = mx + b.  Arbitrarily choosing to use the point (4, 6) and using m = 1/2, we get:

6 = (1/2)(4) + b, or b = 4.

Then the desired equation is y = mx + b, or y = (1/2)x + 4

Answer:

C

Step-by-step explanation:

The question states that Car A after two hours is at 95. We can represent this as (2, 95). We know the slope is 40, which means we can find the y intercept of Car A using point slope form: y = 40(x - 2) + 95. y = 40x + 15. This means that Car B is 5 miles east of car a, as the Y intercept of Car B is 5 greater.

Step-by-step explanation:

-16 + 3n = - 8 - 5n

Bringing like terms on one side

3n + 5n = - 8 + 16

8n = 8

n = 8/8

N = 1

Answer:

n=1

Step-by-step explanation:

-16+3n=-8-5n

-16+8=-5n-3n

-8=-8n

-8n=-8

n=1

Proof:

-16+3n=-8-5n

-16+3(1)=-8-5(1)

-16+3=-8-5

-13=-13

Answer:

(-50) x 30 = -1850 + 350

-1500 = -1500

true

Answer:

Step-by-step explanation:

It is example of "Distributive Law":

                                                         a × (b + c)  =  a × b  +  a × c

When we multiply a number by a group of numbers added together we get the same answer as when we do each multiply separately then add them.

Of course, if you don't remember the distributive law, you can verify it just by doing the operations on both sides of the equality:

(-50) × [37 + (-7) ] = (-50) × 37 + (-50) × (-7)

(-50) × [30]         =    (-1850) + 350  

  - 1500             =          - 1500          ← it's true

Answer:

Option B is the correct option.

Step-by-step explanation:

[tex] \mathsf{x + x + 2 + 2x = - 2}[/tex]

Collect like terms

[tex] \mathsf{4x + 2 = - 2}[/tex]

Move constant to R.H.S and change its sign

[tex] \mathsf{4x = - 2 - 2}[/tex]

Calculate

[tex] \mathsf{4x = - 4}[/tex]

Divide both sides of the equation by 4

[tex] \mathsf{ \frac{4x}{4} = \frac{ - 4}{4} }[/tex]

Calculate

[tex] \mathsf{x = - 1}[/tex]

Answer:

-2

Step-by-step explanation:

Because it says it in the problem.

Since you don't know the value of x you make that a zero.

You add the x's and you get zero.

Answer:

2 x 10 8 x 1 .349 x 1

Step-by-step explanation:

Answer:

a=1

Step-by-step explanation:

35a-29=14-8a

35a+8a=43a

43a-29=14

14+29=43

43a=43

A=1

Answer:

a=1

Step-by-step explanation:

first you distribute for 7(5a-4) so you get 35a - 28 - 1 =14 - 8a.

then you combine like terms so you get 35a - 29 =14 - 8a.

then you do it again which gives you 43a = 43.

divide both sides by 43 to get a by itself and you get a = 1

Answer:

3 inches by 1 inches or 6 inches by 2 inches. Both answera are correct

Step-by-step explanation:

just an equivalent ratio

The measurement pairs that could be the dimensions of Rectangle B are;

The scaled copy of a shape is derived if the original figure is dilated by a constant

Given the measure of the sides of rectangle A:

Length = 9in

Width = 3in

Get the dilation factor

Dilation factor k = ratio of the sides

k = 9/3

k = 3

This means that rectangle B must also have the same scale factor as A.

The possible dimension pairs are 6in by 2in and 3in and 1in since the ratio of their sides is also 3;

k = 6/2 =3

k = 3/1 = 3

Answer:

x = 3

Step-by-step explanation:

Perform the indicated multiplication.  We get  

8x - 6 - 8 = 4 + 2x

Combining the x terms results in:

6x - 14 = 4

Isolate x by adding 14 to both sides:

6x = 18

Find x by dividing both sides by 6:

x = 18/6 = 3

x = 3

The solution or the value of x for the given linear equation 2(4x-3)-8=4+2x is x = 3.

Given that:

2(4x - 3) - 8 = 4 + 2x

Use the distributive property on the left-hand side.

(2 × 4x - 2 × 3) - 8 = 4 + 2x

(8x - 6) - 8 = 4 + 2x

Using the associative property:

8x + (-6 - 8) = 4 + 2x

8x - 14 = 4 + 2x

Subtract both sides by 2x.

8x - 2x - 14 = 4

6x - 14 = 4

Add 14 on both sides.

6x = 18

Divide both sides by 6.

x = 3

Hence, the value of x is 3.

Hey There!!

The answer to this is: isosollese triangle has 2 equal sides that are longer than legnth of base

perimiter=15.7

equation is 2a+b=15.7

so if the longer side is 6.3, wat is legnth of base

we know that identical sides are bigger so 6.3 is one of the identical sides

2a means the 2 idneical sides

2(6.3)+b=15.7

12.6+b=15.7

subtract 12.6 from btohs ides

b=3.1

Thus, answer is base=3.1 cm
