B because n = children and there are always two adults so
2+n
<span>The expression representing the complement of an angle (x):
(90 - x)
:
The expression representing the supplement of an angle (x)
(180 - x)
:
"the complement of an angle is 18 degrees more than 1/3 its supplement."
(90 - x) = (180-x) + 18
:
90 - x = 60 - x + 18; found one third of 180
:
90 - x = 78 - x
:
90 - 78 = -x + x
:
12 = +x
Multiply equation by 3 to get rid of the denominator
3(12) = 3*x
36 = 2x
x =
x = 18 degrees</span>
Answer:
The first term is 12. The common difference is 4.
Step-by-step explanation:
The difference between the third and seventh terms is
36 - 20 = 16
The 7th term is the 4th term after the 3rd term, so the common difference is
16/4 = 4
Answer: The first term is 12. The common difference is 4.
so you divide 258.5 miles by 5.5 hours
by doing this you will be finding the unit rate
Answer: 47 miles in 1 hour
Total coins=46 There are 10 dimes, so it is 10/46. If you reduce it the answer is 5/23. That is not one of the visible options, but there is no option for B so I could be right!
