Uh...Yea... Sorry about this, but I"m trying to study and I need someone to walk me through, missed a lot of school. fyi, when there's a / its under the entire string before it until you hit the inequality symbol.

Tony Bowled 135 and 145 in his first two games. Write and solve a compound inequality to find the possible values for a third game that would give him an average between 120 and 130, inclusive.

1. 120 <= 135+145+n/3<=145; 120<=n<=140

2. 135 <= 120+140+n/3<=145; 80<=n<=85

3. 120 <= 135+145+n/3<130; 80<n<110

4. 120 <= 135+145+n/3<=130; 80<=n<=110

according to your explanation,

#1 is
120 ≤ (135+145+n)/3 ≤ 145
120 ≤ (280 + n)/3 ≤ 145
times 3
360 ≤ 280 + n ≤ 435
subtract 280
80 ≤ n ≤ 155

do the others the same way

To find the possible values for Tony's third game that would give him an average between 120 and 130, inclusive, we need to write and solve a compound inequality.

First, let's break down what we know:

Tony bowled 135 and 145 in his first two games.
The average is calculated by summing all the scores and dividing by the number of games played.

Let's assume the third game's score as 'n'. The average between 120 and 130 (inclusive) can be expressed as:

120 <= (135 + 145 + n) / 3 <= 130

To solve this compound inequality, we need to isolate 'n' in the middle.

Multiply all parts of the inequality by 3 to clear the fraction:

3 * 120 <= 3 * (135 + 145 + n) / 3 <= 3 * 130

360 <= 135 + 145 + n <= 390

Combine like terms:

360 + 280 <= n <= 390

640 <= n <= 390

However, this is an invalid interval because the lower bound is greater than the upper bound. So there seems to be a mistake in the provided options.

The correct compound inequality should be:

120 <= (135 + 145 + n) / 3 <= 130

After solving, the correct answer should be:

40 <= n <= 50
