Answer:
This equation can be solved by using y = kx.
Since y = 25 when x = 60,
25 = 60k and if we solve for k then k= 5/12.
That means the equation we're using is
y = (5/12)x.
Plug in y = 30 and you get
30 = (5/12)x
Solve for x
30 * (12/5) = x
360/5 = x
x = 72
Answer:
The area is 7850 square inches
Step-by-step explanation:
Given the circumference, we want to calculate the area
mathematically, the circumference is;
C = 2 pi r
So r is C/2 pi
Area = pi * r^2
Substitute value for r from circumference;
Area = Pi * c^2/4pi^2
Area = C^2/4pi
Area = 314^2/4 * 3.14
Area = 7850 Inches square
The first expression could be written as 3x + 12 and the second could be written as 2x + 6.
In order to find these, count the number of x's you see in each question. Then use that number as the coefficient to x in your statement. The first problem has 3 and the second has 2.
Then add the numbers of 1's together to get the constants at the end of the expressions. The first has 12 and the second has 6.
