Find values of x that satisfy the inequality 17>2x+1117 > -2x + 11. Circle all applicable options: 111\frac{1}{11}, 2917-2 \frac{9}{17}, 349-3 \frac{4}{9}.

STEP 1

Assumptions
1. We are given the inequality 17>2x+1117 > -2x + 11.
2. We need to determine which of the given numbers satisfy the inequality.
3. The given numbers are: 256,123256,123, 111\frac{1}{11}, 2917-2 \frac{9}{17}, 3-3, 349-3 \frac{4}{9}, and 15,678-15,678.

STEP 2

First, we need to isolate the variable xx on one side of the inequality. To do this, we will subtract 11 from both sides of the inequality.
1711>2x+111117 - 11 > -2x + 11 - 11

STEP 3

Simplify the inequality by performing the subtraction.
6>2x6 > -2x

STEP 4

Now, we need to solve for xx. Since 2x-2x is multiplied by 2-2, we will divide both sides of the inequality by 2-2 to isolate xx. Remember that dividing or multiplying both sides of an inequality by a negative number reverses the inequality sign.
62<x\frac{6}{-2} < x

STEP 5

Perform the division to find the value of xx.
3<x-3 < x

STEP 6

The inequality 3<x-3 < x means that xx must be greater than 3-3. We will now check which of the given numbers are greater than 3-3.

STEP 7

Check option (a) 256,123256,123:
Since 256,123256,123 is much greater than 3-3, this number satisfies the inequality.

STEP 8

Check option (b) 111\frac{1}{11}:
Since 111\frac{1}{11} is greater than 3-3, this number satisfies the inequality.

STEP 9

Check option (c) 2917-2 \frac{9}{17}:
Since 2917-2 \frac{9}{17} is greater than 3-3, this number satisfies the inequality.

STEP 10

Check option (d) 3-3:
Since 3-3 is not greater than 3-3, it does not satisfy the inequality.

STEP 11

Check option (e) 349-3 \frac{4}{9}:
Since 349-3 \frac{4}{9} is less than 3-3, it does not satisfy the inequality.

STEP 12

Check option (f) 15,678-15,678:
Since 15,678-15,678 is less than 3-3, it does not satisfy the inequality.

STEP 13

The numbers that satisfy the inequality 17>2x+1117 > -2x + 11 are:
(a) 256,123256,123, (b) 111\frac{1}{11}, and (c) 2917-2 \frac{9}{17}.
