ANSWER
Find out the how much fluid should be drained and replaced with pure antifreeze so that the new mixture is 60% antifreeze .
To proof
let us assume that the fluid should be drained and replaced with pure antifreeze be x .
As given
A radiator contains 10 quarts of fluid, 30% of which is antifreeze.
Now write 30% in the decimal form

Now write 60% in the decimal form

After drained and replaced the fluid with pure antifreeze than the quantity becomes = ( 10 - x )
The quantity of antifreeze is

The fluid should be drained and replaced with pure antifreeze so that the new mixture is 60% antifreeze .
than the equation becomes

solyving
100x +300 - 30x = 600
70x = 300

x = 4.28 quarts (approx)
Hence 4.28 quarts (approx) fluid should be drained and replaced with pure antifreeze so that the new mixture is 60% antifreeze .
Therefore the option (c.) is correct .

Answer:
The solution to the given inequality is a > 8.
Step-by-step explanation:
For this problem, we have to solve for the inequality.
9a - 24 > 48
add 24 on both sides of the inequality.
9a > 72
Divide 9 on both sides of the inequality.
a > 8
So, your solution would be a > 8.
<span>2x+17=5x-10
2x - 5x = -10 -17
-3x = -27
x = 9
answer
x = 9</span>
