15% of 20 gal = 0.15 * 20 gal = 3 gal, so the solution contains 3 gal of salt.
If we add <em>x</em> gal of water to the solution, we end up with (20 + <em>x</em>) gal of solution. We want the new mixture to have a concentration of 10%, or
10% of (20 + <em>x</em>) gal = 0.1 * (20 + <em>x</em>) gal = 2 + 0.1<em>x</em> gal
of salt.
The amount of salt in the tank hasn't changed. Solve for <em>x </em>:
2 + 0.1<em>x</em> = 3
0.1<em>x</em> = 1
<em>x</em> = 10 gal
Answer:
Cumin has the least price per ounce
Step-by-step explanation:
1. Divide each spice price to the size
Cumin -> 4.80/1.5= 3.2
Ginger -> 3.60/ 0.8= 4.5
Nutmeg -> 6.30/ 1.8= 3.5
Thyme -> 4.50/ 1.25= 3.6
Answer:
B, y = 4x + 1
Step-by-step explanation:
to get it into y- intercept form we need to write it in the form y = mx + b
-8x = 2 - 2y, move 2y to the other side and -8x to the other side they both become positive.
2y = 8x + 2, dividing each by 2
yields y = 4x + 1

1 hour = 60 minutes, so 3 hours = 3 * 60 = 180 minutes.
Her total time was 3 hours and 28 minutes, so 180 + 28 = 208 minutes.
Divide her total time by total miles run:
208 minutes / 26 miles = 8 minutes per mile.
