1. Isolate the y. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
First, multiply 12 to both sides
-y/12(12) = 6(12)
-y = 6(12)
-y = 72
Isolate the y. Divide -1 from both sides
-y/-1 = 72/-1
y = -72
-72 is your answer for y
--------------------------------------------------------------------------------------------------------------
2. Isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
x/4 = 8
First, multiply 4 to both sides
x/4(4) = 8(4)
x = 8(4)
x = 32
32 is your answer for x

Answer:
The radius of a sphere hides inside its absolute roundness. A sphere's radius is the length from the sphere's center to any point on its surface. The radius is an identifying trait, and from it other measurements of the sphere can be calculated, including its circumference, surface area and volume. The formula to determine the volume of a sphere is 4/3π multiplied by r, the radius, cubed, where π, or pi, is a non terminating and non repeating mathematical constant commonly rounded off to 3.1416. Since we know the volume, we can plug in the other numbers to solve for the radius, r.
-
Multiply the volume by 3. For example, suppose the volume of the sphere is 100 cubic units. Multiplying that amount by 3 equals 300.
-
Divide this figure by 4π. In this example, dividing 300 by 4π gives a quotient of 23.873.
-
Calculate the cube root of that number. For this example, the cube root of 23.873 equals 2.879. The radius is 2.879 units.
Answer:
No solution, a triangles angles must measure up to 180 degrees, and that clearly isnt close to it. Therefore, the answer is no solution. An obtuse is an angle greater than 90 degrees, whereas an acute is less.

Answer:
x=-2,y=-4
Step-by-step explanation:
By dividing to lowest terms
5x – 5y = 10= x-y=2.......(1)
6x – 4y = 4=3x-2y=2........(2)
By elimination method
Multiply equation (1) by 3 so as to correspond with equation (2)
3(x-y)=3(2)
3x-3y=6..........(3)
Multiply equation (2) by 1 so as to correspond with equation (1)
1(3x-2y)=1(2)
3x-2y=2..........(4)
Then equation (3)-equation (4)
(3x-3y=6)
-
(3x-2y=2)
__________
-y=4
y=-4
Substitute y=-4 into equation(1)
x-(-4)=2
x+4=2
x=-2
Therefore x=-2,y=-4
