Simplifying
y+10+2y+50=180
reorder the terms:
10+50+y+2y=180
combine like terms: 10+50=60
60+y+2y=180
da da da da dah
and you get
y=40 simplifying
23.
assuming you mean

first term is n=1, so 1²+3=1+3=4
2nd is n=2 so 2²+3=4+3=7
3rd is n=3 so 3²+3=9+3=12
the first 3 terms are 4,7,12
24.
5th term is 5²+3=25+3=28
10th term is 10²+3=100+3=103
difference is 103-28=75
1/8= 1/8
3/4= 6/8
1/8 + 6/8 = 7/8
Answer:
3(2n-9)
Step-by-step explanation:
used distributive property
6n - 27 = (3 · 2n) - (3 ·9)
6n - 27 = 3(2n - 9)
