20x26=520
The answer is D 520.
Hope it helps.
Since the painting is hung in center of a rectangular wall ,the distance between them on either side will be the same.so we can divide the length of the painting and wall by 2.we will get 2.4/2=1.2 feet and 20/2=10 feet .10-1.2=8.8 feet gives the distance between the right edge of the painting and right edge of the wall
Let X be the first and second number.
X+X = 18
+ X-X = 2
2X = 20 (divide both sides by 2
X = 10
Substitute the values to get the second number
10+X = 18
X = 18 -10
X = 8
Therefore, the numbers are 10 and 8
An equation of the line is :
where m is the slope ; so we have :
Can you find the value of
?
Answer:
x = 1, y = 4
Step-by-step explanation:
y = 4x
x + y = 5
Since 4x is equal to the variable y, we can substitute it in for y in the second equation.
x + (4x) = 5
Solve for x.
x + 4x = 5
5x = 5
5x/5 = 5/5
x = 1
Now that we have solved for x, we need to solve for y.
y = 4x
x = 1 so substitute the x with 1.
y = 4(1)
y = 4
We can plug both of our answers into any one of the given equations to check our work
x + y = 5
x = 4 and y = 1
4 + 1 = 5
5 = 5
