Answer:
14.5
Step-by-step explanation:
You would plug 5 into the equation for m and have w = 1.5 (5) + 7
Then you would multiply 1.5 and 5 and get 7.5 and then add 7 and get 14.5
Answer:
<em>1min = 0.25miles</em>
5.25miles / 0.25miles = 25 = 25minutes
Step-by-step explanation:
<u>Hope this is right I'm not the best at worded time/distance math questions.</u>
1. Each term in this polynomial has a common factor of 
:
2. Not sure what the "vertical method" is, but I would guess it refers to some way of visualizing the distributive property.
3. You can use the same approach as in (2), or recall that 
:
4. Recall that a difference of squares can be factored as 
. So
Hi
1 mile = 5280 feet
at 90 mile per hour, you have 5280 *90 = 475 200 feets
an hour is 60*60 = 3600 second
so in 1 second the train travel : 475 200 /3600 = 4752 /36 = 132 feets
so in 10 seconds : 132*10 = 1320 feets.
Answer:
There is a vertical change of 3 units down.
