Answer:
Step-by-step explanation:
In order to evaluate a function at a given x-value, plug in that value into the actual function
Let's remember that 1 pound equals 0.0005 tons, so if we multiply 0.0005 x 20,000 the answer is 10, so 20,000 pounds equal 10 tons.

The answer to (-5 × 2) 3 = -30.
Answer:
40 grams of 13% alcohol solution and 10 grams of 18% alcohol solution.
Step-by-step explanation:
13%(x) + 18%(50-x) = 14%*50g Multiply them all
0.13x + (9-0.18x) = 7
0.13x-0.18x + 9 = 7 Simplify the equation and subtract 0.13x from 0.18x
9-0.05x = 7 Add 0.05x to each side
9 = 7+0.05x Subtract 7 from both sides
0.05x = 2 Multiply each side by 100
5x = 200 Divide both sides by 5
x = 40
50 - 40 = 10
40 grams and 10 grams
