Answer:
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

2x-3y=1
+2x+3y=2
4x=3 substitute 3/4 for x in the first equation..you get y=2/9.
x=3/4
5 trumpet players
let s represent saxophone players and t trumpet players
thus t = s - 10 → ( 10 less than saxophone players)
also s = 3t = 3( s - 10)
solve s = 3( s - 10)
s = 3s - 30
subtract s from both sides of the equation
0 = 3s - s - 30
0 = 2s - 30
add 30 to both sides
30 = 2s
divide both sides by 2
= s ⇒ s = 15
number of trumpet players = 15 - 10 = 5
The area of a rectangle is equal to length times width in which the perimeter is equal to 2 times the sum of length and width. A circle's circumference is equal to 2pi*r. Area of circle is pi*r^2. In this case,
Rectangle A: A= lw = l*(p/2 - l)
Circle: A = pi*r^2 = pr/2
let as say r = l , then A of the circle is greater.
