Fill in each blank with an integer (signed number).
(a) -5 - 1 = -5 + blank
(b) -1 - blank = -1 + 7
(a) -5 - 1 = -5 + (-1)
(b) -1 - (-6) = -1 + 7
Fill in each blank with an integer (signed number).
(a) 4-(-3) = 4+ [
(6) 1-6=1+ П
(a) 4 - (-3) = 4 + 3
(b) 1 - 6 = 1 + (-5)

Graph the inequality below on the number line.
a>4
1234567891011 -1-2-3-4-5-6-7-8-9-10-11
To graph the inequality a > 4 on the number line, we start by drawing a line and marking a point above the number 4 to represent all values greater than 4. We use an open circle on 4 since the inequality is not inclusive of 4. Then, we draw an arrow going to the right to represent all values greater than 4 on the number line.
Here is the graphed inequality:
---> (-infinity) ... -4 -3 -2 -1 0 1 2 3 4o _________> (infinity)
There are two bags containing only orange and yellow marbles.
Bag A has 7 orange marbles and 13 yellow marbles.
Bag B has 1 orange marble and 4 yellow marbles.
A marble is randomly chosen from each bag.
List these events from least likely to most likely.
Event 1: choosing an orange marble from Bag A.
Event 2: choosing a blue marble from Bag A.
Event 3: choosing a yellow marble from Bag B.
Event 4: choosing an orange or yellow marble from Bag B.
Least likely
Most likely
Event , Event , Event , Event
Least likely:
Event 2: Choosing a blue marble from Bag A. (There are no blue marbles in Bag A, so the probability of this event happening is 0.)
Event 1: Choosing an orange marble from Bag A. (There are more yellow marbles than orange marbles in Bag A, so the probability of choosing an orange marble is lower compared to choosing a yellow marble.)
Event 3: Choosing a yellow marble from Bag B. (There are more yellow marbles than orange marbles in Bag B, so the probability of choosing a yellow marble is higher compared to choosing an orange marble.)
Most likely:
Event 4: Choosing an orange or yellow marble from Bag B. (Since Bag B has only one orange marble and 4 yellow marbles, the probability of choosing either an orange or yellow marble is higher compared to the other events.)
