Answer:x = 16
Step-by-step explanation: Make the equation 8/9=x/18: Cross multiply to get 9x=144 and divide both sides by 9 to get 16
Hope this helps, HAVE A BLESSED AND WONDERFUL DAY! As well as a great Superbowl Weekend! :-)

Answer:
106°
Step-by-step explanation:
These angles are alternate interior, therefore they are equal to each other.
Answer:
They are 108 8th graders at Jefferson Middle School
Step-by-step explanation:
324 x 5/12 = 135 7th graders
324 x 3/12 = 81 9th graders
324 x 4/12 = 108 8th graders

Answer: x = 140 (choice C)</h3>
========================================================
Explanation:
Focus on the upper semicircle. It's composed of the arc pieces that are 30 degrees, x degrees, and y degrees. The y is the missing unmarked portion of the upper semicircle.
Subtract the 30 and y degree angles, divide by 2, and set that result equal to 10. This will help us solve for y
(30-y)/2 = 10
30-y = 10*2
30-y = 20
-y = 20-30
-y = -10
y = 10
Because the 30, x and y arcs form a semicircle, this must mean the three arcs add to 180 degrees
30+x+y = 180
30+x+10 = 180
x+40 = 180
x = 180-40
x = 140
I would first suggest turning them all to one thing, like all decimals, or fractions. I chose decimals.
5.2, -5.6, 3.9, √21. To solve the square root, you have to simplify it. There is the square root of 3, times the square root of 7 which gets 21. These can't be simplified, so we can't simplify through that. But, the closest whole number that is a square root is 16. You can check by multiplying the same number together twice. Doing this will get you about 4.58
5.2, -5.6, 3.9, and ≈ 4.58. This is a simple ordering problem now.
It ends up as -5.6, 3 9/10, √21, 5.2
There are 2 decimals, one negative. There is one square root, and one mixed number. The square root is an infinite decimal when simplified
