A triangle has a perimeter of 50. If 2 of its sides are equal and the third side is 5 more than the equal sides, what is the length of the third side?

Let x = length of the equal side Sketch the figure P = sum of the three sides 50 = x + x + x + 5 3x = 50 – 5 3x = 45 x =15 The length of third side = 15 + 5 =20

Michael scores a 95, 87, 85, 93, and a 94 on his first 5 math tests. If he wants a 90 average, what must he score on the final math test?

Answer is 86 To solve for the final score: Add the five past test scores and you get 454. Then set up an algebraic equation where you add 454 to x, which is the final test score, and divide by six, because you want the average for 6 tests now. You make this equation equal to 90 because that is the average Michael wants and solve for x:
