3.14​

Answers

Answer:

14

Step-by-step explanation:

The diameter is the length from one point on the circle to another, passing through the center. The radius is the length from a point on the circle to its center, so we can always find the diameter by doubling the radius. In this case, with a radius of 7, our diameter is 7 · 2 = 14

A variable needs to be eliminated to solve the system of equations below. Choose the correct first step.
-9x + 4y = 17
9x + 7y = 5

A. Subtract to eliminate x.
B. Subtract to eliminate y.
C. Add to eliminate y.
D. Add to eliminate x.

Answers

Answer:

Add to eliminate X that way it will be much easier to solve the system of equations.

Step-by-step explanation:

-9x + 4y = 17

9x + 7y = 5

11y = 22

Last step is to divide both sides by 11 and your answer should come to 2!
