Hannah's set is (2, 4, 5, 7). Which number makes 3x + 2 = 17 true?
x=5
Write an inequality to show that a temperature t is warmer than -8°C and colder than 2°C.
Then name one possible integer value of t.
-8 < t < 2;
Integer example: t = -3
Solve: -3y + 5 < 8.
Give the inequality solution and one integer solution.
-3y < 3 → y > -1
Integer Examples: 0, 1, 2

Ben's fundraiser needs at least $1,200. There is a setup fee of $64 and profit of $12 per shirt. Write an inequality for shirts s and find the minimum integer s needed.
Work:
12s - 64 ≥ 1200 →
12s ≥ 1264 →
s ≥ 105.333... →
minimum whole shirts: 106
Solve and write the solution set: 4x - 7 > 13

If 0.5t + 2 = 7.5, what is t?
t=11
Explain how | -12 | and | -5 | relate to which temperature is warmer: -12°F or -5°F. Then state which is warmer.
| -12 | = 12, | -5 | = 5 measure distances from 0; -5°F is warmer because -5 is to the right of -12 on the number line
