3. The sum of three consecutive numbers is 132. What is the smallest of the three numbers?
43 is the smallest of the 3 numbers
<em>calculation...</em>
<em>x + (x+1) + (x+2) = 132</em>
<em>3x + 3 = 132 -3</em>
<em>3x=129
</em>
<em>x=129/3
</em>
<em>
x=43 (answer for the 1st number)</em>
<em>43+1=44 (answer for the 2nd number)</em>
<em>43+2=45 (answer for the 3rd number)</em>
add them all to make sure they equal to 132
<em>43+44+45=132
</em>
<em>132=132</em>
4. Sandy sold half of her comic books and then bought 8 more. She now has 16. How many did she begin with?

Answer:
(-1,4)
Step-by-step explanation:
Step 1) Change both equations to slope intercept form
3x+y=1 ---> y=-3x+1
5x+y=-1 ---> y=-5x-1
Step 2) Plot lines accordingly on graph
Lines intersect at (-1,4)
