Answer:
C. Amount needed to fence around a circular garden
Step-by-step explanation:
The Circumference of a circle can be referred to as the length of the circle. It also called the perimeter of a circle.
The circumference of a circle can be defined as the distance roundabout a circle.
The circumference of a circle is calculated mathematically as:
a) 2πr or
b) πD
Where r = radius of the circle.
D = Diameter of the circle
From the above question, the situation can be modeled by circumference of a circle based on the definition that the circumference of a circle is the distance around a circle is Option C. "Amount needed to fence around a circular garden"
<u><em>Answer: 333x and x=333. *The answer must be have positive sign.*</em></u>
Step-by-step explanation:
distributive property: a(b+c)=ab+ac
add numbers.
30+7=37
9*37x
multiply numbers.
9*37=333
<em><u>=333x and x=333</u></em>
Hope this helps!
Thanks!
Have a great day!

The first blank is "y", the second blank is "x", and the third blank is 1:3.
The system has one solution
Step-by-step explanation:
Let us revise the type of the solutions of a system of equations
- One solution if the coefficients of x or/and y are different in the simplest form of the two equations
- Infinite many solutions if the coefficients of x , y and the numerical terms are equal in the simplest form of the two equations
- No solution if the coefficients of x and y are equal and the numerical terms are different in the simplest form of the two equations
The system of equations is:
y = 2x - 12 ⇒ (1)
y = 3x + 12 ⇒ (2)
∵ The equations are in its simplest form
∵ The coefficients of x in the two equations are different
- That is the 1st case above
∴ The system has one solution
Let us prove that by solving the system
To solve the system of equations equate (1) and (2) to find x
∵ 3x + 12 = 2x - 12
- Subtract 2x from both sides
∴ x + 12 = -12
- Subtract -12 from both sides
∴ x = -24
- Substitute the value of x in equation (1) or (2) to find y
∵ y = 3(-24) + 12
∴ y = -72 + 12
∴ y = -60
∴ The solution of the system is (-24 , -60)
The system has one solution
