2x - 10 + 3x - 10 = 90
5x - 20 = 90
5x = 90 + 20
5x = 110
x = 110/5
x = 22
2x - 10......2(22) - 10 = 34 <== one angle
3x - 10......3(22) - 10 = 56 <== the other angle
Answer:
n/4 - 3 OR 1/4n - 3
Step-by-step explanation:
First, let's assign a variable to Emily's number. Let is be <em>x</em>.
Now all we have to do is go through the problem step by step.
"She finds 1/4 of the number..."
There are two ways you can do this. You can either multiply n by 1/4 (1/4n), or you can divide by 4 (dividing by four is the same as finding 1/4 of a number). For this example let's divide by four
n/4
"...and then subtracts 3."
All we have to do is subtract 3 from n/4
n/4 - 3
REMEMBER: like I said, there are two possible options. You can either have n/4 or 1/4n. They mean the same thing
So will be 5+5 + 2sqrt2 +2sqrt2 = 10 + 3 +3 = 16 rounded

Answer:
102
Step-by-step explanation:
The range of the data can be calculate by subtracting the min from the max. In this case, the min is 10 and the max is 90. The range is 90 - 10, or 80.
