Answer:
14
Step-by-step explanation:
The diameter is the length from one point on the circle to another, passing through the center. The <em>radius </em>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

Answer:
<u>The correct answer is x = 5 2/3 - 7 2y/3</u>
Step-by-step explanation:
1. Let's solve the equation for x
3x + 23y = 17
3x = 17 - 23y (Subtracting 23y at both sides)
3x/3 = 17/3 - 23y/3 (Dividing by 3 at both sides)
x = 17/3 - 23y/3
2. Proof of 17/3 - 23y/3 as the value of x
3x + 23y = 17
3(17/3 - 23y/3) + 23y = 17 (Multiplying the values inside the parenthesis)
17 - 23y + 23y = 17
<u>17 = 17</u>
<u>It has been proved that x = 17/3 - 23y/3</u>
<u>3. </u>However we can simplify
17/3 - 23y/3
<u>5 2/3 - 7 2y/3</u>
<u>There isn't a system of equations that will allow us to find y</u>
