Question

the perimeter of an isosceles triangle is 73 cm. the base measures 3 cm more than one half the measure of a leg. what is the measure of each side of the triangle

Answer 1

let each leg's length be x cm
so the base is (1/2)x + 3

so ....

x + x + x/2 + 3 = 73
2x + x/2 = 70

my suggestion: multiply each term by 2, and it becomes very easy
