Answer:
5
Step-by-step explanation:
5 + 4 + 3 − 8 + 7 − 6
= 9 + 3 − 8 + 7 − 6
= 12 − 8 + 7 − 6
= 4 + 7 − 6
= 11 − 6
= 5
100 miles in 4 hours. The unit rate would be 25 miles per hour.
100miles / 4hrs = 25 miles per hour
Therefore, for every hour you travel, you will gain 25 miles. Or for every 25 miles you travel, you've spent 1 hour traveling it.
y = 25x
where y is the total miles traveled, 25 is the constant unit rate, and x is the number of hours traveled.
for example: you traveled for 8 hours and you want to know how long you've traveled while maintaining the rate of 25mph. Just use the formula
y = 25x
y = 25(8)
y = 200 miles. you have traveled 200 miles in 8 hours.
12. S=p/5
13. A=wh
14. P=a+b+c
15. A=bh/2
16. A= p-b-c
Multiplying ratios is just like multiplying fractions.
Ex:
5:10 = 5/10
5:10 · 2:20 = 5/10·2/20.
keep 5/10,
simplify 2/20 to 1/10,
multiply 5·1, and 10·10, and the answer is 5/100 or .05
