9514 1404 393
Answer:
60
Step-by-step explanation:
Let x represent the number of members last summer. Then 90% more is 1.9x. We are told this is 114, so we have ...
1.9x = 114
x = 114/1.9 = 60
There were 60 members last summer.
To evaluate for tan 5x/4 we proceed as follows
5x/4
=5/4*150
=225
which is in quadrant III.
This implies that the value of tan will be positive, hence:
tan 225=tan (270-225)
tan 225=tan 45
using right angle with length of the legs being unit, then
tan 45=1
hence
tan 5x/4=1

Answer:
n/5 - 11 = -13
Step-by-step explanation:
We must do the division first, before the subtraction:
"the quotient of a number and 5" is n/5."
"11 subtracted from this result" comes out to n/5 - 11 = -13.
This is the answer. We were not asked to simplify it. But if we want to simplify it, we add 11 to both sides, obtaining n/5 - 2.
