Nawmi had 6 pairs of shoes. She then bought some more pairs and now has 9 pairs of shoes. Set up an equation (do not need to solve) to represent this situation.
6 + x = 9
6 * -2
-12
6x + 7 = 19
x = 2
(x÷3) - 7 = 2
x = 27
WILDCARD: Who was the first US president?
George Washington
Passy can frost 3 cupcakes each minute. If she has 27 cupcakes frosted, how long has it been?
Set up an equation AND solve WITH units.
3x = 27, x = 9
1/7 * 5/3
5/21
6x + 4 - 2x = 16
x = 3
WILDCARD: How many bones are in the human body?

If no one got this correct, I will give points to the closest!
|x + 4| = 3
x = -1, -7
Ketila is 3 miles from school. She starts running further from school at a rate of 8 miles per hour. She is now 19 miles from school. How far has she run?
Set up an equation to represent this, you do not need to solve.
3 + 8h = 19
6 - (-5)
-1
x + 3 = -6 + 4x
x = 3
3x + 2 = 4x + 4
x= -2
2|x - 7| = 4
x = 9, 5
Esther is working on an essay and types 45 words per minute. Then, her younger sibling hits the backspace button and deletes 60 words. If Esther's word count is now 270, how many minutes has she been typing?
Set up an equation AND solve AND include units
45x - 60 = 270, x = 6 minutes
Solve AND simplify. 1/6 + 8/12
10/12 --> 5/6
4 ( -4 + m) = -6 (m - 4)
m = 5
-13 + 6n = -7 (5n - 4)
n = 1
-2 |3-2x| + 4 = -2
x = 0, 3
The sum of two consecutive numbers is 123. Write an equation AND solve what those two consecutive numbers are.
x + x + 1 = 123 OR 2x + 1 = 123
