Answer:

the numbers are 67 and 14

Step-by-step explanation:

let the other number be x

first number = 5x - 3

second number = x

5x - 3 + x = 81

6x = 81 +3

6x = 84

x = 84/6

x = 14

first number = 5x -3

= 5(14) -3

= 70 - 3

= 67

Second number = x

= 14

The circumference of a circle can be found using the formula C = 2r. Which is an equivalent equation solved for r? r = C r = C(2

vaieri [72.5K]

Answer:

r equals StartFraction C Over 2 pi EndFraction

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

where

r is the radius of the circle

Solve for r

That means -----> isolate the variable r

Divide by 2π both sides

$\frac{C}{2\pi}=\frac{2\pi r}{2\pi}$

Simplify right side

$\frac{C}{2\pi}=r$

Rewrite

$r=\frac{C}{2\pi}$

r equals StartFraction C Over 2 pi EndFraction
