The empty jug weighs 0.75 lb

With the 3c, the total weighs 2.25 lb. That means:

3c + empty jug = 3c + 0.75 = 2.25

3c = 2.25 - 0.75
3c = 1.5
 and 1c = 0.5 (so c is a constant -or the slope-)

Then the equation is:

y = 0.5x + 0.75

Why is 4b-7-3b+9 equal to b+2
rodikova [14]
The first expression can be simplified by combining like terms.

First, the terms "4b" and "-3b" can be combined to form "b"
Then, the terms "-7" and "9" can be combined to form "2"

Finally, we simply put these two final terms together, to form "b+2"

Hence, 4b-7-3b+9 is equal to be + 2.

Hope this helps!
