Jai bought a helmet and a pair of skates. The helmet cost £40.
He sold both items for £172.
Jai made a 135% profit on the cost of the helmet and a 60% profit on the total cost.
What was the percentage profit on the skates?
Give your answer to 1 decimal place.

In a certain pentagon, the interior angles are a,b,c,d,e where a,b,c,d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

Pllz me also i will report if you are in for the 1. complete the table by converting each decimal to a fraction. repeating decimals. 0.31 0.125 0.1607 2. describe any patterns you noticed when converting the decimals in the table above.

Who can me with this algebra for your guys.
