Answer: $144
Step-by-step explanation:
8 tiles = $192
1 tile = $24
2 tiles = $48
192 - 48 = 144
she returned 2
8 - 2 = 6
6 tiles = $144
2x-7=29
"Seven less than" => minus 7.
"Two times <u>a number</u>" => 2x (x is the unknown number)
"is twenty-nine" => =29
Putting it all together,
-7 + 2x = 29
or
2x-7=29
(if you were wondering x is equal to 18)
