Answer:
n=42
Step-by-step explanation:
The first step is to open the brackets by multiplying the vale before the brackets to the values inside the brackets giving attention to the signs which gives:
3n-15-2n-16=11
Then we collect like terms together.
3n-2n-15-16=11
evaluating the above equation we get
n-31=11
n=11+31
=42
It goes into 855, 19 times.
I think the answers are: a = 60°, b = 45°, c = 36°.
It’s rise over run so 3/2
26-22x is the correct answer
