Answer:
(4, 7)
Step-by-step explanation:
The midpoint formula is (((x1 + x2)/2), ((y1+y2)/2)))
x1 +x2 = 1 +7 = 8
8/2 = 4
y1 + y2 = 10 + 4 = 14
14/2 = 7
(4, 7) is the midpoint
The prime factors are 1,3,11,33
Answer: 60
Step-by-step explanation: multiply four by 15 in this case take four 15's and add them all up

Answer: 2 < x < 7</h3>
=======================================================
Explanation:
The 85 degree angle is smaller than the 90 degree angle (aka right angle). That must mean 5x-10 is smaller than 25
At the same time, 5x-10 must be larger than 0 to avoid having a 0 length or negative length.
So overall we can say 0 < 5x-10 < 25
-------------
Let's isolate x
0 < 5x-10 < 25
0+10 < 5x-10+10 < 25+10 ...... adding 10 to all sides
10 < 5x < 35
10/5 < 5x/5 < 35/5 .... dividing all sides by 5
2 < x < 7
This says that x is between 2 and 7, but we cannot have x equal either endpoint.
