Using an Equation with Two Variables to Solve a problem
Try
This isosceles triangle has two sides of equal length, a,
that are longer than the length of the base, b. The
perimeter of the triangle is 15.7 centimeters. The
equation 2e +b-15.7 can be used to find the side lengths.
If one of the longer sides is 6.3 centimeters, what is the
length of the base?
cm
b b
is Activity

Answer 1

Explanation:

Your question has typographical errors. The equation is 2a + b = 15.7, not 2e+b-15.7

2a + b = 15.7

b = 15.7 - 2a

since a > b, a = 6.3 cm

b = 15.7 - 2·6.3 = 3.1 cm
