Answer:
2d +18
Step-by-step explanation:
use distributive property:
a(b+c)
= ab+ac
Answer:
200 divided by 60
Step-by-step explanation:
310, since 4 is not up to 5, then 2 round off to 0
Let V, be the rate in still water and let C = rate river current
If the boat is going :
upstream, its rate is V-C and if going
downstream, its rate is V+C,
But V = 5C, then
Upstream Rate: 5C - C = 4 C
Downstream rate: 5C+C = 6C
Time = distance/Rate, (or time = distance/speed) , then:
Upstream time 12/4C and
Downstream time: 12/.6C
Upstream time +downstream time:= 2h30 ' then:
12/4C + 12/.6C = 2.5 hours
3/C + 2/C = 5/2 (2.5 h = 5/2)
Reduce to same denominator :
5C = 10 and Rate of the current = 2 mi/h
Answer:
290
Step-by-step explanation:
To solve this problem you multiply 29 by 100 and then divide the total by 10 as follows:
(29 x 100) / 10
Therefore, you can derive that 10 percent of 290 equals 29.
Note that the answer provided is rounded to the nearest two decimals if necessary.
