Answer
x = 21
HOS = 68
Explanation
The arrows beside x point to 12 and 6, which is a straight angle. Straight angles always add up to 180 degrees.
So that means 3x+5 plus 5x+7 must equal 180 degrees.
3x+5+5x+7 = 180
Combine like terms.
8x+12 = 180
Subtract 12 from both sides.
8x = 168
x = 21
But BE CAREFUL.
The problem is asking for the angle HOS.
To do this, just substitute what you got for x into the expression.
3(21)+5 = 68
The value of HOS is 68 degrees.

Answer:
6
Step-by-step explanation:
x = number of questions answered correctly
y = number of questions answered incorrectly
18x - 24y = 72
x = 2y
18*(2y) - 24y = 72
36y - 24y = 72
12y = 72
y = 72/12
y = 6

Answer:
8 1/4 or 8 2/8
Step-by-step explanation:
6+1= 7
5/8+5/8= 10/8 or 1 2/8
1 2/8 + 7= 8 2/8
