Hi there!
Since the total weight the box can hold is 8 pounds, and she filled up 2/4:
8 * 2/4 = 4
There were 4 pounds in the box.
Hope this helps!
Answer:
r=2
Step-by-step explanation:
r + 8 r + 11 = 29
( 1 + 8 ) r + 11 = 29 9 r + 11 = 29
Now we can isolate and solve for r while always keeping the equation balanced: First, subtract 11 from each side of the equation:
9 r + 11 − 11 = 29 − 11
9 r + 0 = 18
9 r = 18
Now we can divide each side of the equation by 9 to get
r : 9 over 9 = 18 under 9
1 r = 2
r = 2
X^2 - xy + xy - Y^2
=
X^2 - Y^2
6x + 4 - x = 2(x+1)
First combine like terms on the left side:
6x-x - 5x
So you have 5x+4 on the left side.
Then use the distributive property on the right side:
2(x+1) becomes 2x +2
Now you have 5x +4 = 2x +2
Subtract 4 from each side:
5x = 2x -2
Subtract 2x from each side:
3x = -2
Divide both sides by 3:
x = -2/3
