I got 78.66, is there an answer choice like that?
Answer:
5 1/8 - 2 7/8 =
3 -6/8 =
2 2/8 =
2 1/4 =
2.25
Step-by-step explanation:
The youngest child is 8 years old.
8 x 2 = 16
8 + 13 +15 +16 = 52
52 / 4 = 13
If interpreted as shown, the order is shown in the lines following
1+sin(x)/1-sin(x)-1-sin(x)/1+sin(x)
=1 + ((sin(x))/1) - sin(x) -1 - (sin(x)/1) + sin(x)
which is completely meaningless for the purpose of this question.
The left-hand side is
common denominator is (1-sin(x))(1+sin(x)), so
using a^2-b^2=(a+b)(a-b)
