Answer:
40x +18(x -3) = 468
Step-by-step explanation:
If x is collected from each of 40 repeat customers, the amount collected from them is 40x.
If $3 less is collected from each of 18 new subscribers, the amount collected from them is 18(x -3).
The total amount collected is 468, so we have ...
40x +18(x -3) = 468

Calculators Rock!!!
Answer:
the answer to this will most likely be nine 9
The side opposite the 30o angle is 1/2 W. That is just a property of a 30 - 60 - 90 triangle. Use that fact to set up the pythagorean relationship.
w^2 = (1/2 w)^2 + (7 * sqrt(3)) ^2
w^2 = 1/4 w^2 + 49*3
w^2 = 1/4 w^2 + 147
3/4 w^2 = 147
w^2 = 147 * 4/3
w^2 = 49 * 4 = 196
w = sqrt (196)
w = 14
