Answer:
Yes
Explanation:
10 miles in 12 days means 30 miles in 36 days
You are running about .83 (repeating decimal) miles a day, so if your goal is 25 miles in 30 days it would be .83 times 30. Which is 24.9, if you look at it with the repeating decimal you should be right on track.
I hope this helps.

Step-by-step explanation:
4x + 10 = 2y - 4x ( add 4x to both sides )
8x + 10 = 2y , that is
2y = 8x + 10 ( divide through by 2 )
y = 4x + 5
then
x = 2 : y = 4(2) + 5 = 8 + 5 = 13
x = 4 : y = 4(4) + 5 = 16 + 5 = 21
x = - 1 : y = 4(- 1) + 5 = 1
so table is
x y

2 13
4 21
- 1 1
$6.40
All beads and pendants = $19.20, and the beads equal $12.80, so 12.80 + ? = 19.20. So you would use the equation. 19.20 - 12.80, which equals 6.40.
Substitute y = 15x to the equation y = 25 + 12.5x:
15x = 25 + 12.5x <em>subtract 12.5x from both sides</em>
2.5x = 25 <em>divide both sides by 2.5</em>
x = 10
Substitute the value of x to the equation y = 15x:
y = (15)(10)
y = 150
<h3>
Answer: x = 10 and y = 150</h3>
