<em>The slope is 2x.</em>
<em>X represents the slope.</em>
<em>Y represents the total cost or value</em>
<em>The +2 represents the Y-intercept.</em>
<em>I know this all for a fact because the equation is written out in the slope-intercept form which is commonly displayed like this:</em>
<em>Y = MX + B</em>

3a+11=7a-13
move 7a to the other side
sign changes from +7a to -7a
3a-7a+11= 7a-7a-13( combine like terms)
3a-7a+11= -13
-4a+11= -13
move 11 to the other side
sign changes from +11 to -11
-4a+11-11= -13-11
-4a= -13-11
-4a= -24
divide both sides by -4 to get a by itself
-4a/-4= -24/-4
Answer: a= 6
Answer: Each notebook cost $2.55
Step-by-step explanation:
You divide $15.30 by 6, which equals $2.55.
It would be 12% of 50
50 * 12/100 = 600/100 = 6
so, 6 cars are red
