36 liters
8 • 4 (8 liters for 4 cars)
2 • 2 (2 liters spilled for 2 sets of 2 cars)
Answer:
-3x + 9
Explanation:
Because these two integers that is - and - is said to be added and write the sign of of greater or bigger number.
Solve. Note the equal sign. What you do to one side, you do to the other. Remember to follow PEMDAS.
First, distribute 5 to all terms within the parenthesis
5(w - 1) = (5)(w) + (5)(-1) = 5w - 5
Next, simplify. Combine like terms
5w - 5 - 2 = 5w + 7
5w - 7 = 5w + 7
Next, isolate the variable. Add 7 to both sides, and subtract 5w from both sides
5w (-5w) - 7 (+7) = 5w (-5w) + 7 (+7)
5w - 5w = 7 + 7
0 = 14 (Untrue).

~<em>Rise Above the Ordinary</em>
Answer:
95.15%
Step-by-step explanation:
We have that the mean (m) is equal to 20, the standard deviation (sd) 3
They ask us for P (x <25)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / sd
We have all these values, replacing we have:
z = (25 - 20) / (3)
z = 1.66
With the normal distribution table (attached), we have that at that value, the probability is:
P (z <1.66) = 0.9515
Which means that the probability that it arrives before 25 minutes is 95.15%
13,000 • 3 = 1 hour = 39,000
Now we take the one hours worth 39,000 • 48 (hours in two days) = 1,872,000
Hope this helps!
