You know that e= mc^2. In order to find the Value of mc, you have to take squareroot on both sides. So,
squareroot of e= mc
Answer:
The height of each story is 10 ft
Step-by-step explanation:
see the attached figure to better understand the problem
Let
x -----> the height of each story
The linear equation that represent this problem is
Solve for x
Combine like terms
Subtract 6 both sides
Divide by 2 both sides
Rewrite
therefore
The height of each story is 10 ft
{y/y=-9,-3,0,5,7} the range are the y values of a function or relation
Answer:
The price of Apples is $3.30 and the price of Oranges is $2.
Step-by-step explanation:
So first treat the price of apples and the price of oranges as variables. Let's say that the price of an apple is X and the price of an orange is Y.
1 Apple and 1 Orange is $5.30, so the equation is 1X + 1Y = 5.30
1 Apple and 2 Oranges is 7.30 so the equation is 1X + 2Y = 7.30
Now, adjust one of the equations so you can know the price of one thing in relation to the price of the other.
1X + 1Y = 5.30 can become 1X = 5.30 - 1Y
Now substitute this into the other equation.
1X + 2Y = 7.30 becomes 5.30 - 1Y + 2Y = 7.30. Now, either combine the Y values or combine the price values.
5.30 + 1Y = 7.30
Y = $2
Now that you have the Y value, replace it in one of the equations.
1X + 2$ = 5.30
1X = 3.30
Answer:
Y=3x-2
