Answer:
The correct answer is:
w-12 20
Explanation:
We first find the average of the two ends of the inequality:
(19.88+20.12)/2 = 40/2 = 20
This will be the number subtracted from w in the inequality.
Now we find the difference between this value and the ends:
20-19.88 = 0.12
20.12 - 20 = 0.12
This will be what our absolute value inequality ends with; the "answer" part, so to speak.
Since this inequality is written in compact form, it must be an "and" inequality; this means the absolute value inequality must be a "less than or equal to."
This gives us
w -12 20
We need to look at factors of 2, which are only 2 and 1... How do we get them to add to -3? Well, they have to be negative.
-2 + -1 = -3
What about the multiplication? A negative × a negative = a positive, so
-2 × -1 = 2
So your answer is
-2 and -1
Answer:
The train going 30 miles in 1/3 hour is going faster than the other train.
Step-by-step explanation:
Calculate each rate by dividing the distance traveled by the amount of time it takes to cover that distance:
30 / (1/3) = 90 mph
20 / (1/2) = 40 mph
