Answer:
The diameter of the floor is 6 yards
Step-by-step explanation:
Here, we are to calculate the diameter of a circular floor that has a circumference of 18.84 yards
Mathematically,
C = π * D
where C is the circumference
Plugging the values of the circumference , we have ;
18.84 = 22/7 * D
7 * 18.84 = 22D
D = (7* 18.84)/22 = 5.99 which is approximately 6 yards
Divide 24 by 6 because that is how many numbers are on the cube which would equal 4
Then multiply 4 and 2 because that's how many possibilities there are of rolling a number less than 4 and is even and the solution is 8
Calculate like terms:
7x-8=8x
7x-8x=8
-x=8
-x/-1=8/-1
x=-8
Answer:
x = -1
y = 4
Step-by-step explanation:
Solving system of linear equations by elimination method.
8x + 3y = 4 ---------------(I)
2x + y = 2 --------------(II)
Multiply the second equation by (-3) and then add them.Thus y will be eliminated and we will obtain the value of 'x'.
(I) 8x + 3y = 4
(II)*(-3) <u> -6x - 3y = -6 </u> {Now add}
2x = -2
x = -2/2
Plugin x = (-1) in any one of the equations. Here I have chosen equation (II)
2*(-1) + y = 2
-2 + y = 2
y = 2 + 2
