Hope it answers your question.
4.7 -7.25x+ 8.623x -3.8
= (4.7 -3.8)+ (8.623x -7.25x) (combine like terms)
= 0.9+ 1.373x
The final answer is 1.373x+ 0.9~
The relation between the width and the length is:
l = 3w + 1 --- (1) Perimeter = 2w + 2l --- (2) Put (1) in (2) » Perimeter = 2w + 2(3w+1) » Perimeter = 2w + 6w + 2 Perimeter = 8w +2
Answer:
42 general admission tickets and 57 youth tickets were sold.
Step-by-step explanation:
Since the ice rink sold 99 tickets for the afternoon session, for a total of $ 915, and general admission tickets cost $ 15 and youth tickets cost $ 5 each, to determine how many of each kind of tickets were sold the following calculation must be performed:
15 - 5 = 10
99 x 5 = 495
915 - 495 = 420
420/10 = 42
99 - 42 = 57
(42 x 15) + (57 x 5) = X
630 + 285 = X
915 = X
Thus, 42 general admission tickets and 57 youth tickets were sold.
