3y + 12 = 27
3y = 15
y = 5
Sam has 3 bottles of water. Together, Sam and Dave have fewer than 12 bottles of water. Write an algebraic inequality where Dave's water bottles are represented by w.
x + 3 < 12
What are at least 2 letters in the alphabet that make horrible variables? Why?
s, l, o --> they look too much like 5, 1, and 0!

Write an algebraic equation to match the scenario: Three consecutive integers have a total of 24. Let n equal the smallest/first integer. Standard form.
n + (n + 1) + (n + 2) = 24
3n + 3 = 24
When would you reverse an inequality symbol while solving an algebraic inequality problem?
When you divide or multiply both sides by a negative number

When dividing fractions, you really do what?
Multiply by the opposite (second) fraction/keep change flip!

6k - 15m + 27
3 (2k = 5m + 7)
Molly goes to the mall and buys 5 pairs of shoes for $16 each. She also 5 pairs of socks for d dollars each. If she spent a total of $102.50, write an algebraic equation that would help you to find the cost of a pair of socks.
Solve the following inequality and graph the solution:
1/3p + 10 (is less than or equal to) 16
1/3p + 10 (is less than or equal to) 16
1/3p (is less than or equal to) 6
p (is less than or equal to) 18

Finish the bad-dad joke: What do sprinters eat before a race?
Nothing, they fast!
Combine Like Terms (standard form):
4/5b - 1/3f - 2/3b + 5 + 3/4f - 2
4/5b + (-2/3b) + (-1/3f) + (3/4f) + 5 + (-2)
12/15b + (-10/15b) + (-4/12f) + (9/12f) + 3
2/15b + 5/12f + 3
Write the answer in expression form:
12x - 3(x - 4y) + 3/4(4x - 16y)
12x - 3(x - 4y) + 3/4(4x - 16y)
12x + (-3x) + 12y + 3x + (-12y)
12x + (-3x + 3x) + (12y + -12y)
12x + 0 + 0
12x
Jimbo is designing a rectangular pool where the length is 3 less than twice the width. It has a perimeter of 42 feet total. If w represents the width, create and solve an algebraic equation for how many feet the width and length of the pool are.
w = width so length = 2w - 3
w + w + (2w - 3) + (2w - 3) = 42
6w - 6 = 42
6w + 48
w = 8 --> width is 8 ft and length is 13 feet
Write and solve an algebraic inequality for the following scenario:
Tiny Tim is planning to grow his pokemon card collection this summer. He has $110 now and by the end of the summer, he wants to still have more than $75. If he buys each card, c, for $4.50, how many cards can he buy and still have more than $75?
110 - 4.50c > 75
-4.50c > -35
1c < 7.78
c < 7 cards... He can buy at most 7 cards this summer
