The circumference of the circle is 9.42 inches, What is the diameter of the circle?
Elena L [17]

EXPLANATION

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

Circumference=2\pi r=2\pi\frac{d}{2}=\pi d

Isolating the diameter:

Diameter=\frac{Circumference}{\pi}

Plugging in the numbers:

Diameter=\frac{9.42}{3.14}=3

Therefore, the diameter is equal to 3 inches.

The equations x + 5 y = 10, 3 x minus y = 1, x minus 5 y = 10, and 3 x + y = 1 are shown on the graph below. On a coordinate pla
natita [175]

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)

Solution of equation 3x-5y= 4 4x+3y=15
12345 [234]
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
