8. 3x-4>38
3x>38+4
3x>42
x>42/3
x>14
So the answer is A. x>14

Answer:
The Average rate of the first plane is 560 mph
Step-by-step explanation:
x = first plane's average rate (in mph)
x−108 = second plane's average rate (in mph)
First planes total distance = 2.25x
Second planes total distance = 1.25(x−108)
2.25x + 1.25(x−108) = 1825
x = 560
Answer:
Step-by-step explanation:
Given expression:
Note: <em>The value of "x" is undefined because the given sum is not an equation. Thus, I will simplify the expression as much as possible. </em>
Let us simplify all the distributive properties stated in the expression.
Apply the distributive property rule <u>[a(b + c) = ab + ac]</u>
Since 5(x) is being subtracted from 5(x), we get:
Finally, let us simplify the sum of the product of (5 and 4) and (5 and 2).

Answer:
108°
Step-by-step explanation:
In order to find the measure of the exterior angle, we first need to solve for a. We know that the sum of a triangles' angles is always 180°.
Now we set up an equation:
180 = 44 + (a + 10) + (180 - 2a)
180 = 44 + a + 10 + 180 - 2a
180 = -a + 234
-54 = -a
54 = a
Because we know that a = 54, we can now solve for the exterior angle:
2(54) = 108
Therefore, the measure of the exterior angle is 108°.
