<h3>Answer:</h3>
x=5, y=2
<h3>Explanation:</h3>
The second equation gives an expression for x that can be substituted into the first equation.
... (y+3) +y = 7 . . . . . .substitute y+3 for x
... 2y + 3 = 7 . . . . . . . colect terms
... 2y = 4 . . . . . . . . . . subtract 3 from both sides
... y = 2 . . . . . . . . . . . . divide both sides by 2
Using the expression for x, we can find its value.
... x = y + 3
... x = 2 + 3 . . . . . . . . . substitute for y
... x = 5
The solution is (x, y) = (5, 2).
Answer:
30
Step-by-step explanation:
30 dived by 5 is 6 then 6 times 5 is 30
Answer:
3/4 divided 4=16 or 0.1875
Step-by-step explanation:
3/4 divided by 4 is easy all you would do is multiply the bottom number by what you are trying to divide which is 4 so you do 4x4 which is 16
B. 18 because you divide the total number of cans by the number of sheets used to make them. 36/2 = 18, 180/10 = 18
Answer:
The radius of these cylinders is approximately 1 foot.
Step-by-step explanation:
According to this graph, the volume of the cylinder is directly proportional to its height, that is, radius remains constant. The expression of direct proportionality:
(1)
Where:
- Volume of the cylinder, in cubic feet.
- Height of the cylinder, in feet.
- Proportionality constant, in square feet.
Besides, the proportionality constant is described by this expression:
(2)
Where 
is the radius of the cylinder, in feet.
If we know that 
and 
, then the radius of the cylinder is:
The radius of these cylinders is approximately 1 foot.
