Wade wants to have at least $55 left, so the sign will be ≤ (greater than or equal to 55) One sweater costs $12. You can use x to represent an unkown number of sweaters, so $12x. You are subtracting 12x by your budget of $175. When put together, the inequality is $175-$12x ≤ $55.
Now to solve. You want to get x alone so subtract 175. You must do this to both sides. Now you have -12x≤ -120. Divide both sides by -12 and your final answer is -120/-12 ≥ 10. (Notice the sign changes when you divide by a negative)
So Wade cannot buy more than 10 sweaters to have $55 left over. Phoo that was a workout. It can be difficult but once you get the hang of it it comes easy. If you need more help just ask :D
See the attached picture for the calculation.

Answer:
b. 156
Step-by-step explanation:
A "perfect square" is the product of <em>an integer that is being multiplied by itself. </em>
<em>Choice a</em>, 625, is a perfect square because it is the product of 25 multiplied by itself.
<em>Choice b</em>, 156, is not a perfect square because you cannot find any integer that can be multiplied by itself that will result in 156 as a product. Therefore, <u>this is the correct answer.</u>
<em>Choice c,</em> 196, is a perfect square because it is the product of 14 multiplied by itself.
Answer:
1/2 of the juice box
Step-by-step explanation:
We see that Karen has 2/3 of her juice box left. Her brother drinks 3/4 of that leftover 2/3.
First, remember that "of" in mathematics usually means to multiply. Here, since the brother drank 3/4 of the 2/3, we multiply the two:
(3/4) * (2/3) = (3 * 2) / (4 * 3) = 6 / 12 = 1/2
We understand this as 1/2 of the entire thing.
So, Karen's brother drank 1/2 of the juice box.
