Answer:   x = 6

Step-by-step explanation:

Angles 1 and 8 are alternate exterior angles, so they are equal.

so you can create an equation to solve for x

12x−20 = 2x+40  Subtract 2x from both sides. Add 20 to both sides

10x = 60

x = 6

if you need the  m∠1, Substitute 6 for x.  (2x+40)°  2(6) +40= 12+40 m∠1= 52°

m∠8=(12x−20)°   12(6) - 20 = 72-20  m∠8 = 52°

Answer:

C

Step-by-step explanation:

find the distance between the two points and divide that by 3 first,

then you estimate the point that is from point A with that 1/3 distance

The coordinate of point C such that point C on AB that is 1/3 the distance from point A to point B is (-3,-2) so option (C) will be correct.

A pair of numbers is used to express a point's position on a coordinate plane using the horizontal and vertical distinctions from the two reference axes. usually represented by pairs of x-values and y-values (x,y).

Coordinate a point with intercept m: n and bounded by coordinate (x₁, y₁) and (x₂, y₂) is given by

x = [m(x₂) + n(x₁)]/(m + n)

y = [m(y₂) + n(y₁)]/(m + n)

Here m = 1/3 and n = (1-1/3) = 2/3

And coordinates A(–7, –6) and B(5, 6).

So,

x = [ 1/3(5) + 2/3(-7) ]/ 1

x = -3

And,

y =  [ 1/3(6) + 2/3(-6) ]/ 1

y = -2

So (-3,-2) will be the coordinate of point C.

Hence "The coordinate of point C is (-3,-2).

Answer: 4

Step-by-step explanation: 2 x 2 = 4 dummy

Answer:

2/4

Step-by-step explanation:

You would have to count the number of units (rise over run)

Answer:

the slope is 1/2 .

Step-by-step explanation:

Answer:

y = 3x+1

Step-by-step explanation:

Well, slope intercept form is y =mx+b, and to find the slope, you have to take two of the examples for y, and divide it by 2 examples of the x, like so:

7- (-5) / 2- (-2) which is 12/4 which is 3, so the slope is 3.

we now can make the first part of the equation:

y = 3x + b

Now we just need "b". To find b, just substitute the x and y values for two values shown on the chart, such as -2 and -5. (They have to be on the same row).

-5 = 3x-2 + b

you get:

-5 = -6+b

which is equal to:

b = 1

So, putting b back in the equation, you get:

y = 3x+1

Answer:

Unit rate = 1.25 inches per yard

Length of fence B on the blueprint = 5 inches

Step-by-step explanation:

We are told that Fence A is 1 1/5 yards long but is 1 1/2 inches long on the blueprint.

This means it's 1.2 yards long but 1.5 inches on the blueprint.

Thus, the unit rate for this blueprint will be; 1.5/1.2 = 1.25 inches per yard

fence B is 4 yards long.

Thus, the corresponding blueprint measurement = 4yards × 1.25 inches/yard = 5 inches.

Answer:

2

Step-by-step explanation:

To find the answer to this question, we need to add the numbers according to their place. Etc if 1 and 4 are together in a hundreds place, we add them together. If both numbers add up together results in a number bigger than 9, we have to regroup.

First, let us find the ones place.

3+5=8

Since the result is not more than 9, we do not have to regroup.

Secondly, we find the tens place.

7+6=13

Since the result is more than 9, we have to regroup.

Regrouping counter:1

Thirdly, we find the hundreds place.

8+4=12

Regrouping counter:2

Hence, your final answer is 2.

The number of times we need to group when summing 873 and 465 is 2.

During addition of two numbers, values are added based on their place values, such that digits with the same place value are added together.

The highest single value that can be obtained when summing values without needing to regroup is 9.

Hence, each time two digits are added such that the value of the sum exceeds 9, then regrouping is required.

Adding 873 + 465

H __ T __ U

8 __ 7 __ 3

4 __ 6 __ 5

(3 + 5) = 8 ( NO NEED TO REGROUP)

7 + 6 = 13 (WE NEED TO REGROUP) SUM exceed 9

(8 + 4 + 1) = 13 (WE NEED TO REGROUP) SUM exceed 9

Hence, the number of times we need to regroup is 2.

Answer:

Let x be the number of hours for 1.74 miles

5.3 miles         3.2 hours

1.74 miles        x

When you cross multiply the above numbers you get the equation:

5.3x = 5.568

x = 5.568/5.3

x = 1.05

Therefore it takes 1.05 hours to walk 1.74 miles.
