Answer:
D
Step-by-step explanation:
Because lets say Length was 3 and Width is a variable of w
3xW=Area
1. 75/300 = x/48 (your proportion)
2. x= 12
3. 30/240 = x/24 (your proportion)
4. x= 3
Your answer would come out to 15 miles total.

Answer:
(x, y) = (7, -1)
Step-by-step explanation:
The expression for x makes it easy to use that for substitution.
3(-7y) +y = 20
-20y = 20 . . . . . collect terms
y = -1 . . . . . . . . . divide by -20
-7(-1) = x = 7 . . . use y in the second equation to find x
The solution is (x, y) = (7, -1).
Answer:
True
Step-by-step explanation:
6x² - 4y - 3x + 6x² + 8x = 12x² + 5x - 4y
Regroup terms on left
6x² + 6x² - 3x + 8x - 4y = 12x² + 5x - 4y
Combine like terms
on left
12x² + 5x - 4y = 12x² + 5x - 4y True
