Let X = science homework.
Then math homework would be 3x ( three times as long).
Now you have math plus science = 64 minutes:
x + 3x = 64
Combine like terms:
4x = 64
Divide both sides by 4:
x = 64 / 4
x = 16
He spent 16 minutes on science and 48 minutes on math.
Answer:
y
Step-by-step explanation:
y is smaller because
1 millimeter = 0.001m
Answer:
The length of each side of the square is 5 meters
Step-by-step explanation:
<u><em>The correct question is</em></u>
A figure is formed by a square and a triangle. total area is 32.5 m^2. the area of the triangle is 7.5 m^2. what is the length of each side of the square?
we know that
The total area of the figure is equal to the area of triangle plus the area of square
so
The area of square is equal to the area f the figure minus the area of triangle
Let
A ----area of the square
Find the length side of the square
Remember that the area of the square is
where
b is the length side of the square
substitute
square root both sides
therefore
The length of each side of the square is 5 meters
Answer:
y = x + 2
Step-by-step explanation:
As the equation of a line is in the form y = mx + c:
Step 1 - Calculate the y intercept
This can be done by looking at the y coordinate where x = 0:
y = mx + c
In the picture, the y intercept is 2 so:
y = mx + 2
Step 2 - Calculate the slope
This can be calculated by:
Get two sets of coordinates:
(0, 2) and (2, 4)
Calculate the changes by subtracting from one another:
So the gradient is 1, meaning the equation of the line is:
