Answer:
2
Step-by-step explanation:
2 is farther right on the number line because it is a positive number while -2 is negative.
Answer:
Step-by-step explanation:
- With the equation's current format, we will have trouble solving with all these fractions. Especially the fraction
is very difficult to deal with, so my first step would be:
- If we multiply both sides by this number, we will be able to get rid of the messy fraction on the right side as well as remove the fraction on the left side. Like so:
- <em>I put the
I multiplied onto each side in fraction form simply for clarity. You do not need to do this.</em>
- After this point, let's put our variable,
, onto one side of this equation and any other integers on the other by adding and subtracting them from both sides.
- Now we divide so that is isolated, and we are done.
Answer:
b. 0.45.
Step-by-step explanation:
The total possible outcome of a probability is 1
Given;
Probability that both lights will be red when she reaches them = 0.22
Probability that the first light will be red and the second light will not be red = 0.33
Probability that the second light will be red when she reaches it = x
These are all the possible outcomes, therefore
0.22 + 0.33 + x = 1
0.55 + x = 1
x = 1 - 0.55
x = 0.45
Option b
Answer:
-5/6
Step-by-step explanation:
Answer:
Caleb arrived first 2 hours before Alyssa
Step-by-step explanation:
To solve the situation, find the speed per hour they were driving by dividing the distance they drove by the time it took.
Alyssa drove 105 miles in 3.5 hours or 105/3.5 = 30 miles per hour.
Caleb drove 168 miles in 4 hours or 168/4 = 42 miles per hour.
Since they both left at the same time and drove the same 210 miles to the beach, Caleb arrived first since he was driving faster.
He arrived in 210/42 = 5 hours.
Alyssa arrived in 210/30 = 7 hours.
He arrived 2 hours before her.
