Answer:
But where are the rectangles??
4x + 7y = 1 ⇒ 12x + 21y = 3
3x + 10y = 15 ⇒ <u>12x + 40y = 60</u>
<u>-19y</u> = <u>-57</u>
-19 -19
y = 3
4x + 7(3) = 1
4x + 21 = 1
<u> - 21 - 21</u>
<u>4x</u> = <u>-20</u>
4 4
x = -5
(x, y) = (-5, 3)

Answer:
40 miles is her goal.
Step-by-step explanation:
The problem says that 24 miles is 60% of her goal for that month.
You cab make a proportion with x being the goal for the whole month.
24/x = 6/10
You cross multiply and get:
6x = 24 x 10
6x = 240
x = 40
40 miles is the answer.
