1 kilometers =1000 meters
0.86km=0.86*1000=860m
John swam 860 meters each day.
1 week = 7 days
3weeks=3*7=21
21*860=18060 m
Therefore he swam 18060 meters in those three weeks.
Answer:
<em>29 minutes more</em>
Step-by-step explanation:
Let m represent minutes
changing the statement to algebra, since the second company charges a different rate at night and weekend we have the equation below;
$19.99 + $0.35m > $29.99
Subtract 19.99 from both sides to isolate m and we have;
$19.99 -$19.99 + $0.35 > $29.99 - $19.99
= $0,35m > $10.00
Divide both side by 0.35 to obtain the value of m;
> 
= m > 28.57
<em>m ⩾ 29 minutes</em>
<em>The second company's will be twenty nine minutes or more costlier than the first company</em>
Answer:
Pedro got 1520 base hits and Ricky got 1243.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of base hits that Pedro got.
y is the number of base hits that Ricky got.
Pedro and Ricky got 2673 base hits last season.
This means that 
Pedro had 277 more hits than Ricky.
This means that 
Replacing in the first equation






Pedro got 1520 base hits and Ricky got 1243.
Y equals 3x-3 is the answer
