7 5/8 =____
+6 6/7=+____
____= ____

Answer:

C

Step-by-step explanation:

From corresponding angles theorem, we can see the 2 angles are equal.

16x+13=18x-1

2x=14

x=7

Done!

Any questions just leave them in the comments and I will answer.

Answer:

Step-by-step explanation:

i think you do 34x + 12

bc it is a same side interior angle and i think that equals 180 and then you

34x+12=180

      -12  - 12

34x=       168

------          ------

34              34

----------------------

i.dk i think it is 5 bc you get 4.98 so you round the 8 and it makes it a 4.10 which is 5

Step-by-step explanation:

Answer:

x = - 6    

Step-by-step explanation:

Equation

1/3 * (-9x +12) = 22                Multiply both sides by 3

Solution

3 * 1/3(-9x + 12) = 22*3

- 9x + 12 = 66                        Subtract 12 from both sides.

-9x = 66 - 12                         Combine

-9x = 54                                Divide by -9

x = 54/-9

x = - 6

Answer:

(5, 1 )

Step-by-step explanation:

Given the 2 equations

3y - 2x = - 7 → (1)

5x + 3y = 28 → (2)

Rearrange (1) expressing 3y in terms of x by adding 2x to both sides

3y = - 7 + 2x

Substitute 3y = - 7 + 2x into (2)

5x - 7 + 2x = 28

7x - 7 = 28 ( add 7 to both sides )

7x = 35 ( divide both sides by 7 )

x = 5

Substitute x = 5 into either of the 2 equations and solve for y

Substituting into (2)

5(5) + 3y = 28

25 + 3y = 28 ( subtract 25 from both sides )

3y = 3 ( divide both sides by 3 )

y = 1

solution is (5, 1 )

Answer:

-(3y-2x= -7)

3y+5x= 28

-3y+2x= 7

3y+5x= 28

7x=35

7x/7= 35/7

x=5

5(5)+3y= 28

25+3y=28

3y= 28-25

3y=3

3y/3=3/3

y= 1

3y-2x= -7

3(1) -2x= -7

3-2x= -7

-2x= -7-3

-2x= -10

-2x/-2=-10/-2

x= 5

chekin

5x+3y=28

5(5)+3(1)=28

25+3=28

28=28

Answer:

greater

Step-by-step explanation:

the reason is because if you allow x to have a value that is less than 3,

[tex] \sqrt{x - 3} [/tex]

will produce a square root of a negative number, and the square root of a negative number requires the use of imaginary numbers, therefore limiting x to greater than or equal to 3 prevents this, also, consideration should be given to the fraction

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

if x has a value of -2 it causes the denominator of the fraction to be 0, the denominator should never be 0, by limiting x to greater than 3 to prevent the problem above you are already taking care of x not being able to be -2 since greater than 3 already excludes -2

Answer:

angle DEC is 45 degrees

Step-by-step explanation:

angle DEC is 45 degrees because it is supplementary to 135 degrees

(with 135 degrees, adds up to 180 degrees)

Answer:

270 seconds

Step-by-step explanation:

Melissa's time = x seconds

Abby's time = (x + 30) seconds

Abby walks at a speed of 8 feet per second, and Melissa walks at a speed of 9 feet per seconds.

But, speed = [tex]\frac{distance}{time taken}[/tex]

For Abby,

8 = [tex]\frac{distance}{(x + 30)}[/tex]

distance = 8(x + 30) ................. 1

for Melissa,

9 = [tex]\frac{distance}{x}[/tex]

distance = 9x ............. 2

From equations 1 and 2, for the same distance;

8(x + 30) = 9x

8x + 240 = 9x

x = 240 seconds

Abby's time = (x + 30)

                    = (240 + 30)

                    = 270 seconds

So that Abby has been walking for 270 seconds when both students had walked exactly the same distance.

The time taken is 270 seconds.

Given that,

Based on the above information, the calculation is as follows:

8(x + 30) = 9x

8x + 240 = 9x

x = 240

So Abby time should be

= 240 +  30

= 270

Answer:

P = 10w

Step-by-step explanation:

Number of point per correct spelling = 10

Number of words spelt correctly = w

Total points, p

P = (number of points per correct spelling * number of words spelt correctly)

P = 10 * w

P = 10w

Answer:

5 miles

Step-by-step explanation:

Hi there!

To find the rate at which Gia can run, you have to divide 4 by 32 to find how many miles she runs per min. When you do that, you get .125 Gia runs .125 miles per min. To find how many miles she runs in 40 min, you multiply .125 by 40 to get 5. This means that Gia runs 5 miles in 40 min.

Answer:

the area of the parallelogram would be 40

to find the area all you need to do it multiply the base by the height. (8×5=40)

since m is parallel to n, this means that the two angles are alternate angles. Hence, 46°=6x-2

Calculate and you should get x = 8°
