Answer:

A. 31.4 feet

Step-by-step explanation:

The formula for circumference is given by

C = pi d

Since we know the diameter is 10 ft

C = pi * 10

pi  is approximately  3.14

C = 3.14* 10

C = 31.4 ft

Answer:

(5,4)

Step-by-step explanation:

multiply each equation by the value that makes the coefficients of x opposite

(-1) · (4x + 6y) = (-1) · 44

4x + 2y = 28

simplify

-4x - 6y = -44

4x + 2y = 28

add the two equations together to eliminate x from the system

      -4x - 6y = -44

<u>+      4x + 2y = 28</u>

              -4y = -16

divide each term by -4

y = 4

substitute the value for y into one of the original equations, then solve for x

-4x - 6y = -44

-4x - 6(4) = -44

-4x - 24 = -44

     + 24   + 24

-4x = -20

divide by -4

x = 5

so, since x = 5 and y = 4 ....

the solution to the independent system of equations can be represented as a point.

hope this helps! :)
