15, because 52 minus 7 is 45, and 45 divided by 3 is 15.
15 x 3 + 7= 52
TSP makes a right triangle with TS and TP being the sides and SP being the hypotenuse.
Using the Pythagorean theorem and the two given sides you can solve for the hypotenuse.
SP = √6^2 + 8^2
SP = √36+64
SP = √100
SP = 10 cm.
It is as 5x's as much.
<em>$0.30 X 5 = $1.50</em>
Hope I helped
