Answer:

27 years

Step-by-step explanation:

In three years, Tom will be 57 + 3 = <em>60 years old</em>.

Since Tom will be twice as old as James at that time, then James will be half his age, or 60/2 = <em>30 years old</em>.

If James is going to be 30 years old in three years, then he is 27 years old now.

Answer: 27

Step-by-step explanation:

Tom is 57 now. In 3 years he will be 60, but also twice as old as his son. 1/2 of 60 is 30. 30 minus the 3 years that hasn’t happened yet equals 27.

1x -8 &lt; 2x + 1<br> What is the largest integer value that makes this inequality true
professor190 [17]

Answer:

The largest integer value that makes the inequality true is 9.

General Formulas and Concepts:
<u>Algebra I</u>

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality

Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify.</em>

1x - 8 < 2x + 1

<u>Step 2: Solve for </u><u><em>x</em></u>

  1. Simplify:                                                                                                            x - 8 < 2x + 1
  2. [Subtraction Property of Equality] Subtract <em>x</em> on both sides:                        -8 < x + 1
  3. [Subtraction Property of Equality] Subtract 1 on both sides:                        -8 < x
  4. Rewrite:                                                                                                           x > -8

∴ we see that any number <em>x greater than -8</em> would work as a solution to the inequality. That would mean the next largest integer, 9, would be our answer.
