7. bridges the total length of wire used in the
cables supporting the golden gate bridge in
san francisco is about 80,000 miles. this is
5,300 miles longer than three times the
distance around earth at the equator. what
is the distance around earth at the equator?

The distance around Earth at the Equator is about 24,900 miles

Step-by-step explanation:

Let

x -----> the distance around Earth at the Equator

we know that

The linear equation that represent this scenario is

Solve for x

Subtract 5,300 both sides

Divide by 3 both sides

Rewrite

therefore

The distance around Earth at the Equator is about 24,900 miles

a² + b²= c²

24² + 7² = c²

c= 25

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
