Answer:
x is the number you have to multiply by the given number to get the whole value
Step-by-step explanation:
5x*7 x=35
By cutting each corner we have that the resulting dimensions are:
27 - 2x
18 - 2x
Height = x
Therefore, the volume of the box in terms of the variable x, is given by:
V (x) = (x) * (27-2x) * (18-2x)
Answer:
The volume of the box in terms of x is:
(27-x) (18-x) x
Answer:
Step-by-step explanation:
From the problem statement, we can setup the following equations:
where 
is the current age of Shobos and 
is the current age of his mother.
Substituting the first equation into the second will allow us to solve for :
Substituting this value into the first equation gives us the age of the mother:
Answer: 37.5%
Explanation:
Percentage is defined as parts of an amount in 100 parts of a basis. This must be stated mathamatically for better understanding and for calculations. It is the ratio:
% = (parts / base) × 100.
In this case you need to express the amount of butter as a part in 100 parts of all purpose flour, which, using the above definition, is:
% butter = (0.75 pounds of butter / 2 pound of flour) × 100
% butter = 0.75 × 100 / 2 = 75 / 2 = 37.5
The answer is expressed as 37.5%.
Answer:
x = 1 y = 2
Step-by-step explanation:
x + 3y = 7
- Subtract x from both sides.
3y = -x + 7
- Divide both sides by 3 to isolate the variable.
y = -1/3x + 7/3
- Plug the value of y into the other equation.
3x + 4(-1/3x + 7/3) = 11
3x - 4/3x + 28/3 = 11
- Add like terms.
5/3x + 28/3 = 11
5/3x = 5/3
x = 1
- Plug the value of x into the equation.
x + 3y = 7
(1) + 3y = 7
3y = 6
y = 2
