A. x=13
Step-by-step explanation:
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.
Would it be
(2r-7)*(2r+7)
?
Distance = 500 miles
Distance of automobile = 10r
r = 50
Distance = 10 x 50 = 500 miles
