Answer:
Therefore, the volume of sphere is 1436.03 cubic units.
Step-by-step explanation:
X=2y
2x+5y=9
substitute the x=2y into the second equation
2(2y)+5y=9
multiple the 2y by 2. 4y+5y=9
combine like terms. 9y=9
divide the 9 out from both sides. y=1
plug the y back into the first equation
x=2(1)
multiply. x=2
your answer is: x=2
y=1
Multiply all 4 an the answer is gonna be the area
Answer:
it is an example of an expression
Step-by-step explanation:
it is an example of an expression because it is asking a question without an equal sign. so its not a question, but an expression
X=-9
-x=9 so x=-9 since you inverse the sign
