Answer:
C.
Step-by-step explanation:
that number line has both -5 and -1. so, you can count the distance between -1 and 2. and count the distance between -5 and 2
The answer is m = 7.
1. (<span>13−m=2(m−4) </span>Regroup terms
2. Expand (<span>13−m=2m−<span>8)
3. </span></span>Add <span><span>m</span></span> to both sides (<span>13=2m−8+<span>m)
4. </span></span>Simplify (<span>2m−8+m</span> to <span><span><span>3m−8)
5. add 8 to both sides (13 + 8 = 3m)
6. </span></span></span>Simplify <span>13+8 to 21
7. </span>Divide both sides by <span><span>33</span></span> (21/3 = m)
8. simplify 21/3 to 7 (7 = m)
9. switch sides ( finally m = 7)
Answer:
To stay within budget, she must use 4.5 gigabytes.
Step-by-step explanation:
Giving the following information:
Under her cell phone plan, Sofia pays a flat cost of $58.50 per month and $4 per gigabyte. She wants to keep her bill at $76.50 per month.
<u>First, we need to establish the total cost formula:</u>
Total cost= 58.5 + 4*x
x= number of gigabytes
<u>Now, we isolate x:</u>
76.5= 58.5 + 4x
18/4= x
4.5= x
To stay within budget, she must use 4.5 gigabytes.
Answer:
Step-by-step explanation:What is the probability of an event that is impossible? Suppose that a probability is approximated to be zero based on empirical results. Does this mean that the event is impossible?
