Answer:
40%
Step-by-step explanation:
Percent means out of 100
Multiply the top and bottom by 20 to get the bottom to 100
2/5 * 20/20 = 40/100
The percent is 40%
Its already an improper fraction.
If you mean mixed number it would be 7 4/7.

Answer:
3x - (15 x 3) = 90
or
3x - 45 = 90
Explanation:
there are 3 boxes. We don't know how many are in them yet, so we write this as 3x. However, we know that we give away 15 to 3 different teachers. 15 x 3 = 45
Therefore the first part is 3x - 45
We also know that in the end we have 90 left.
So our final equation is:
3x - 45 = 90
When you are multiplying and have like bases, then you add the exponents.
2+3=5
3^5
Idk but it can't be 10 or 9.7 bc a triangle's hypotenuse is always longer than its legs
