Answer:

x = 10

Step-by-step explanation:

Diagonals of a rhombus bisect each other at a 90° angle, but most importantly (for this problem), they bisect the opposite angles of the rhombus equally.

This means that the two angles, given by the expressions (6x + 12) and (8x - 8), are equal to each other.

Set them equal to each other in an equation and solve for x.

Subtract 6x from both sides.

Add 8 to both sides.

Divide both sides by 2.

The value of 10 for x will make the given parallelogram a rhombus.

Answer:

7. Inscribed angle

Step-by-step explanation:

7. Inscribed angle

8.

y° = 70°

z° = 140°

8. y° and 70° are the measures of the angles subtended in the same arc. So, they would be equal.

Therefore, y° = 70°

Measure of central angle is two times the measure of the inscribed angle.

Therefore,

z° = 2* 70° = 140°

Answer:

(4× +6)° =+24° =102°+24° = 126°= x=126°

Answer:

If the radius of a circle is 5 inches, the diameter is 10.

Step-by-step explanation:

This is because to find the diameter of a circle sing the radius is to multiply it by two. 5x2=10

So the diameter is 10. If you want to find the radius just reciprocate the process, divide the diameter by 2 and yo will get the radius.

I really hope this helped you out. Make sure to give my answer brainliest. Have a radiant day or night ! :D

Answer:  The answer is 50.24 SQAURE INCHES.

Step-by-step explanation: So this circle is even. 8 up and down. * to the right and left. Now the area needs to be found. If the diameter is 8 inches, your answer should be 50.24 SQUARE INCHES.

Answer:

n is 20

Step-by-step explanation:

If n/8=2.5, then you can just do 8*2.5 to find n. 2.5*8=20

Answer:

n=20 because if you multiple 2.5 and 8 you will get 20 so if you divide 20 and 8 then you get 2.5

Answer:

the sum of interior triangle is 180

so,

92+33+X=180

125x=180

X=180-125

=55

Answer:

x<13

Step-by-step explanation:

Answer:

13

Step-by-step explanation:

|-20| = 20 (anything with | | is absolute value, which is always positive), |7| = 7, 20 - 7 = 13.

quick tip: when you see something like -|#|, that would be negative, but if you saw |-#|, it would be positive.

Answer:

Step-by-step explanation:

Initial value is $400

Value after 9 years is zero

Change in value over 9 years is $400

Rate of change is:

Answer:

Resale value of a refrigerator

The rate of change on the graph :---

(Final amount - initial amount)/(Final year - initial year)

[tex] \frac{(0 -400)}{(9 - 0)} = \frac{-400}{9} =\boxed{-44.44}✓\\ [/tex]

slope is negative as the amount is decreasing every year

The 2nd one should be right

Answer:

B.it will move to the right.

Explanation:

We have 5 newtons of force pushing to the right, and 3 newtons of force pushing to the left. We can place the positive direction on the right hand side and the negative direction on the left.

This means we can think of "3 newtons of force to the left" as the integer -3

That way we can then add 5 to -3 getting 5+(-3) = 2. The result is positive, meaning the net force is pushing to the right. Specifically, 2 newtons of force are pushing to the right.

It's like saying there are 5 people pushing to the right and 3 pushing to the left. From each side, 3 people will pair up and they'll cancel each other out. The 2 extra people pushing right will ultimately win out.

Answer:

Miley can walk a distance of [tex]13\frac{1}{5}[/tex] miles in four hours.

Step-by-step explanation:

Given that:

Distance walked by Miley in [tex]1\frac{2}{3}[/tex] hours = [tex]5\frac{1}{2}[/tex] miles

We will find unit rate in term of hours.

[tex]\frac{5}{3}\ hours = \frac{11}{2}\ miles[/tex]

Multiplying both sides by 3/5

[tex]\frac{3}{5}*\frac{5}{3}\ hour = \frac{11}{2}*\frac{3}{5}\\\\Unit\ rate = \frac{33}{10}\miles\ per\ hour[/tex]

Distance walked in four hours = [tex]4*\frac{33}{10}\ miles[/tex]

Distance walked in 4 hours = [tex]\frac{66}{5}=13\frac{1}{5}\ miles[/tex]

Hence,

Miley can walk a distance of [tex]13\frac{1}{5}[/tex] miles in four hours.

Answer:

-2.1y + 12.9

Step-by-step explanation:

Answer:

12.9-2.1y

Step-by-step explanation:

Use the distributive property to multiply −0.5 by 12y−9.

8.4+3.9y−6y+4.5

Combine 3.9y and −6y to get −2.1y.

8.4−2.1y+4.5

Add 8.4 and 4.5 to get 12.9.

12.9−2.1y
