Can u help me with 5 6 7 and 8

Answer:

1. x = 66

2. C

3. C. 2000

Step-by-step explanation:

1. The first question is x = 66 because to get rid on the fraction you multiply both sides by 4. This leaves you with x + 2 = 68 (minus 2 on both sides) this gives you x = 66.

2. C. Commutative

3. 2000

Plug in

125 = (5)(.0125)(2000)

125 = 125

Hope this helps ya!!

Answer:

simplified:  [tex]\frac{3}{5}[/tex]

unsimplified:  [tex]\frac{12}{20}[/tex]

Step-by-step explanation:

Since the fractions have the same denominator, all we have to do is subtract the numbers in the numerator:

15 - 3 = 12

The difference of the two fractions is [tex]\frac{12}{20}[/tex]. To simplify this answer, divide both the numerator and the denominator by 4:

12/4 = 3

20/4 = 5

The difference in simplified form is [tex]\frac{3}{5}[/tex].

I hope this helps. :)

Answer:

111°

Step-by-step explanation:

The polygon given is a heptagon having 7 sides.

Sum of interior angles of a 7-sided polygon = (n - 2)*180

= (7 - 2)*180

= 5*180 = 900°

Therefore:

126° + 158° + 120° + 125° + 121° + 139° + x° = 900°

Solve for x

789° + x° = 900°

Subtract 789 from each side

x = 900° - 789°

x = 111°

Step-by-step explanation:

Answer:

60 pieces

Step-by-step explanation:

What we know:

There are 12 inches in a foot

There are 5 6-feet lengths of ribbon

So, we simply need to multiply.

Since there are 12 inches in a foot, and we only need 6 inches for each one, we can see that she makes 2 pieces for each foot.

Multiply

2*6=12

She makes 12 pieces for each length of ribbon.

Now multiply it by 5

12*5= 60

She can make 60 pieces from 5 of these length of ribbon.

Hope this helps!

Answer:

slope m = -2, y-intercept b = 1

Step-by-step explanation:

The slope is the change in y over the change in x.

Equation for slope: y2-y1/x2-x1=m

Since they already gave us the two points we just have to decide which one is our y2,y1 and out x2,x1 (which one you chose does not matter). And plug the numbers into the equation and get: -3-1/2-0=m, in this case, m=-4/2 and simplify it into -2. Now we have our slope.

The y-intercept is where the line crosses over the y-axis, and in our case, it is given to us in the (0,1) so our slope is 1.

Hope this helps you

Answer:

the triangle means "change in". so triangle x means the change in the x values and triangle y means change in y values so yeah mental calculate the difference

Answer:

130

Step-by-step explanation:

The two angles add up to be 180 degrees, so you could find the value of the second angle to be 110 degrees, but it is asking for the x value so you would choose 130 since when you subtract 20 from 130 you get 110.

Answer:

[tex]y=\frac{3}{4} x+2[/tex]

Step-by-step explanation:

y=mx+b

We have two points (0,2) and (4,5).

2=m(0)+b --> So b=2

5=4m+2

4m=3

m=[tex]\frac{3}{4}[/tex]

[tex]y=\frac{3}{4} x+2[/tex]

Answer:

Hope I'm not too late for this...

(look below)

Step-by-step explanation:

For the first part:

1. b = -1, m = 2

The y-intercept (b) is the value of y when x = 0. In this case, we can see that when x = 0, y = -1 so the y-intercept is -1.

The slope was found using the equation slope (m) = (y2-y1) / (x2-x1) and two points. (Note, you can choose any two points, I just chose the first two.)

(5,9) (-2,-5)

slope = (y2-y1) / (x2-x1)

slope = (-5-9) / (-2-5)

slope = -14/-7

slope = 2

I used the same steps as shown above:

2. b = 2, m = -3

For the second part:

1. y = 2x - 1

2.y = -3x + 2

I basically plugged in the values for m and b into the equation, y = mx + b.

Graphs:

The way to graph a line is to plot at least two points and draw a line through them. You can graph it using either the equation or the table. I used the table since it is much easier to find the points that I need.

Below I have included references to what the graph should look like if you need to check your work.

The one in blue is for the equation y = 2x - 1. This should help you get a visual of what the correct graph looks like.

The one in green is for the equation y = -3x + 2.

I hope this helped!
