Below are the answers to Monday's test review worksheet.

1) a > 30.25
On the graph, you should have an open circle at 30.25 and shade to the right.
2) Open circle at 3.5 and shade to the right.
3) p < 20 AND g > 12
4) 10
30
50
5) m = 12w
6) No the number line does not represent x >=1. The solution x = 1 should be included on the graph and should be a closed dot.
7) x < -8
8) x = 22
9) 1.25m + 5 < 40 OR 40 > 1.25m + 5
10) d = 6m
11) g = 22
12) m = 20/27
13) x = 12
14) 32
15) x < 9
Open circle at x = 9 and shade to the left

I do not understand number 9

9) In this example, Uber charges $5 to get in the car in addition to $1.25 per mile (m). Melissa only has $40 to spend (no more). Write an inequality showing how many miles she can ride without going over $40.

m = number of miles
5 + 1.25m <= 40 (less than or equal to)

I dont understand number 7

7) Recall from the previous chapter when we plotted integers on the number line. Imagine a thermometer being a vertical number line. Any numbers below 0 are negative!

So, 8 degrees below zero is -8. As you get colder, the numbers are getting smaller.

x < -8

I dont understand number 7 either.

I dont get how to solve number 13

Mr. Berchtold

1/27/2020 09:36:22 pm

13) 25 - x = 13

In other words, 25 minus what number is equal to 13? You can count up from 13 until you get to 25. When you count up from thirteen, it takes 12 more numbers to reach 25.

On your test tomorrow, you can check your four answer choices to see which answer makes the equation true (the left side must equal the right side)

For number nine shouldn’t it be less than or equal to

Ry understand now

Can you help me with 4

Mr Berchtold

I won't be home until late tonight and I do not have the worksheet with me. Remember, area of a parallelogram is base × height, where the base and height are perpendicular (90 degree angles are formed)
