x = -4

x = -30

Part Two: Inequalities

Multiple Choice

What would you need to do next in the following situation: While solving -4x > 8, you first divide by -4 on both sides of the inequality...

Add 8 to both sides of the inequality

Change the answer from a negative number to a positive number

Multiply both sides of the inequality by x

Check your work!

Multiple Choice

Solve the following inequality for x:

-\frac{1}{2}x\ +\ 5\ <\ 9

x < -8

x > 8

x < -2

x > -8

Multiple Choice

Sandy sold 22 tickets to the school barbecue. She sold more than twice the number of tickets Teresa sold. This situation can be represented by the inequality 2t < 22 where t is the number of tickets Teresa sold. Given this inequality we know Teresa sold less than ______ tickets.

Check your work!

Multiple Choice

I was solving 5p + 5 < 45 on the board. I added 5 on both sides and got 5p < 50 and then divided by 5 on both sides and got p < 10 as my solution set. What, if anything did I do wrong?

Nothing, this is correct!

I should have subtracted 5 on both sides first rather than adding 5

I should have multiplied by 5 on both sides rather than dividing by 5

I should have reversed the inequality sign

Multiple Choice

I was solving

\frac{1}{2}m\ -\ 6\ >\ 4

. I added 6 on both sides and got

\frac{1}{2}m\ >\ 10

. I then divided by 2 on both sides and got m > 5. What, if anything did I do wrong?

Nothing, this is correct!

I should have subtracted 6 on both sides rather than adding 6

I should have multiplied by 2 on both sides rather than dividing by 2

I should have reversed the inequality sign.
