Answer:
<u>x=-1.5</u>
Step-by-step explanation:
To solve for x, you need to rearrange so the x is on one side of the "=" by itself.
So To do that, first you need to subtract 1/4 on both sides of the "=". This leaves you with 1/2+x=-3/4-1/4. You can simplify the -3/4-1/4 to -1 (-4/4). So, you now have 1/2+x=-1.
The next step is to subtract 1/2 on both sides of the "=". This leaves you with x=-1-1/2. Again, you can simplify the -1-1/2 to -3/2 which can be written as -1.5. So, you now have x=-1.5, which is the final answer.
The question may ask you to write your answer in the form of a fraction, in which case your answer x=-3/2. If the questions wants it written as a mixed number, your answer would be -1 1/2.

The amount of plastic wrap needed is gotten by finding the area of the triangle, multiplying it by two, and adding it to 72.9 cm²,
<h3>
Area</h3>
Area is the amount of space occupied by a three dimensional object.
To calculate the amount of plastic wrap needed to wrap the triangular prism. We add the area of all the surface of the triangular prism
Amount of plastic = (2 * area of triangle) + (3 * 5) + (3 * 10.3) + (3 * 9)
Amount of plastic = (2 * area of triangle) + 72.9 cm²
The amount of plastic wrap needed is gotten by finding the area of the triangle, multiplying it by two, and adding it to 72.9 cm²,

∴ Total money withdrew =
Hence, the expression to determine the total amount of money she withdrew is and Total money she withdrew is -$22.5
Answer:
$43.20
Step-by-step explanation:
20% of $50.00 is $10.00. $50 - $10 is $40. 8% of $40 is $3.20. Since this is tax, you must add it. $40+$3.20 = $43.20
