Answer:
It will take 29 days to lay the track
After 18 days the crew still has 77 miles of track left to lay
Step-by-step explanation:
203÷7
=29 days
L= 203 - 7(18)
L= 203 - 126
L= 77
Answer:
80,000 + 1.04 to the forth power
Step-by-step explanation:
First term is initial number
Second term is one plus the percent as a decimal (if it’s an increase)
Then to the power of 4 assuming that there are 4 year in between 2016 and this year, 2020
68/80 is a fraction
34/40
17/20 is simplest form of fraction
percent means parts out of 100 so x/100
20 times 5=100 so
17/20 time 5/5=x/100=85/100 or 85%
decimal is normally a power of 10 so
85/100=0.85
To find slope, use the formula:
(y2-y1)/x2-x1)
So here is what it will look like:
(9--7)/(1--3)
Since you are subtracting a negative, then it turns unto a positive so you are adding the numbers together.
(9+7)/1+3)
16/4
4
The slope of the line is 4/1 or 4. Which means that you will go up or "rise" 4 and go to the left or "run" 1.
Hope this helps!
-6r+5
the two like terms are the ones with R. combine -4r and -2r to get -6r
