6 / 88 = 21/x
cross multiply
(6)(x) = (21)(88)
6x = 1848
x = 1848/6
x = 308 <==
1. 3rd one
2. f(x) = 7x - 5
f(2) = 7(2) - 5
f(2) = 14 - 5
f(2) = 9
3. c(n) = 0.75n - 0.25
4. (0,0)(2,4)
slope = (4 - 0) / (2 - 0) = 4/2 = 2
answer is : y = 2x
Answer:
In order for the appropriate answer to be given, you need to include the original measurements as well.
27 + x is the simplified expression.
