EXPLANATION
Since the circumference of the circle is 9.42, we can get the diameter by applying the following relationship:

Isolating the diameter:

Plugging in the numbers:

Therefore, the diameter is equal to 3 inches.
Answer:
The question is missing, so I will answer all the solution for each possible system of two equations.
Step-by-step explanation:
The equations
x + 5 y = 10 (red)
3 x - y = 1 (blue)
x - 5 y = 10 (green)
3 x + y = 1 (purple)
are shown in the picture atatched. The intersection between two lines is the solution of their system.
<u>system:</u>
x + 5 y = 10 (red)
3 x - y = 1 (blue)
<u>solution</u>: (0.938, 1.813)
<u>system</u>:
x + 5 y = 10 (red)
x - 5 y = 10 (green)
<u>solution</u>: (10, 0)
<u>system</u>:
x + 5 y = 10 (red)
3 x + y = 1 (purple)
<u>solution</u>: (-0.357, 2.071)
<u>system</u>:
3 x - y = 1 (blue)
x - 5 y = 10 (green)
<u>solution</u>: (-0.357, -2.071)
<u>system</u>:
3 x - y = 1 (blue)
3 x + y = 1 (purple)
<u>solution</u>: (0.333, 0)
<u>system</u>:
x - 5 y = 10 (green)
3 x + y = 1 (purple)
<u>solution</u>: (0.938, -1.813)
3x-5y=4------eq1
4x+3y=15-------------eq2
multiply 3 to first eq and 5 to second eq.
9x-15y=12
20x+15y=75
subtract both eqs
29x=87 x=3 so put x in eq 1
3(3)-5y=4
5y=5
y=1
