<u>Answer:</u>
9. x = 12
10. x = 31
<u>Step-by-step explanation:</u>
9. Corresponding angles are equal, so technically you can move that (7x - 20) to be diagonal with the (4x + 16). Along with the corresponding angle, diagonal angles are equal to each other. Therefore you can set (7x - 20) equal to (4x + 16) to find x.
7x - 20 = 4x + 16
Solve
3x - 20 = 16
3x = 36
x = 12
Therefore x is equal to 12
<u>Check:</u>
4(12) + 16
= 64
7(12) - 20
= 64
10. All angles in a triangle have to add up to 180 degrees. Therefore, you can write your equation like this:
x + 2x + 25 + 2x = 180
Combine like terms
5x + 25 = 180
Solve
5x = 155
x = 31
Therefore, x = 31.
<u>Check:</u>
31 + 2(31) + 25 + 2(31) = 180
31 + 62 + 25 + 62 = 180
180 = 180

Answer:
31.41592...
Step-by-step explanation:
If the radius of the circle is 10 inches, the circle's circumference is 31.4 because you calculate circumference as follows:
x = r * pi (3.1415926535)
Answer:
Step-by-step explanation:
I hope this helps you
12x^2+29x-8
4x -1
3x +8
(4x-1)(3x+8)
The range is the difference in between the largest and the smallest number in the set.
On a box and whisker plot, the maximum and the minimum are shown as the dots on the furthest right and left side. On this particular one, they would be the dots on 29 and 17.
All you have to do is
29-17
and you get 12
The range of the data is 12.
Hope this helps!
