If the number is 5 or greater you round it up
if its four or less you round down
Solution:
we have been asked to find
The expression is equivalent to 
we can simplify the given expression as below
Hence the simplified expression , equaivalent to the given expression is 1/2.
Answer:
C
Step-by-step explanation:
We are given that FGH is a triangle, which means that...
Angle F + Angle G + Angle H = 180
Start by substituting the given angle measurements into the equation:
4x+2+13x-7+3x+5=180
Combine like terms
20x=180
Divide both sides by 20 to isolate x
x=9
Plug 9 back in for x to solve for each angle
Angle F = 4(9)+2=36+2=38
Angle G = 13(9)-7=117-7=110
Angle H = 3(9)+5=27+5=32
If you use substitution the should be answer 30
