The variable y is given.
now, substitute y in the second equation to get
-4x - (-4x-7) = 7
then we solve
first distribute
-4x+4x+7=7
combine like terms
0+7 = 7
7 = 7
because the answer is true, the solution to this system is “all real numbers”

Answer:
Part 1) The volume of the cylinder is
Part 2) The volume of the sphere is
Part 3) Determine <em>the difference</em> of the volumes to find the leftover space
Part 4) The volume of space in the cylinder that is not being taken up by the sphere is about
Step-by-step explanation:
step 1
Calculate the volume of the cylinder
we have
-----> the height is the diameter of the sphere
substitute the values
step 2
Calculate the volume of the sphere
we have
substitute the values
step 3
Determine the difference of the volumes to find the leftover space
therefore
The volume of space in the cylinder that is not being taken up by the sphere is about
<h2>Answer: </h2>
I will use 6 cups of oats and 1 cup of honey to make 12 cups of granula
.
<h3>Explanation:
</h3>
Let x be the number of cups of oats and let y be the number of cups of honey. Given statement can be expressed in fractions as
½ x / ¼ y = 12
4x/2y = 12
2x/y = 12
x/y = 12/2 = 6/1
x=6, y=1
Therefore number of cups of oats = x = 6 cups
Number of cups of honey = y = 1 cup
