Answer:

7.9% reduction.

Step-by-step explanation:

Kerrin's initial weight can be calculated by 13(14)+7=189 pounds.

Three months later he weighs 12(14)+6=174 pounds.

The difference between 189 and 174 is 15 pounds.

\frac{15}{189}≈.0793651 or 7.9%.

What is the justification for each step in solving the inequality?
Fed [463]

Step-by-step explanation:

3x+\frac{5}{8}\geq 4x-\frac{1}{2}

Subtract 5/8 on both sides

To subtract 5/8 we make the denominators same

3x\geq 4x-\frac{1*4}{2*4}-\frac{5}{8}

Addition or Subtraction property of order is used

3x\geq 4x-\frac{9}{8}

Subtract 4x on both sides

Addition or Subtraction property of order is used

-x\geq -\frac{9}{8}

Now divide both sides by -1

Multiplication or Division property of order is used

\frac{-x}{-1} \geq \frac{-\frac{9}{8}}{-1}

Multiplication or Division property of order is used

x\leq \frac{9}{8}

Answer:

B

Step-by-step explanation:

If A = {1, 2, 3} and B = {1, 2, 3, 4, 5}

We say that A is a subset of B, since every element of A is also in B.
