Answer: The conversion factor between km and m is 1 km = 1000 m, and between hr and seconds, it is 1 hr = 3600 s. Let's first convert 9 km/hr to m/hr.
9 km/hr x (1000 m / 1 km) = 9000 m/hr
Then use the 2nd conversion factor to convert hr to seconds.
9000 m/hr x (1 hr / 3600 s) = 9000 / 3600 m/s = 5/2 m/s
Step-by-step explanation:
Answer:
658.8 miles
Step-by-step explanation:
first divide 54.9 by 60. then multiply that by 12 times 60
Division can be used. For example
50/16=3.125gallons
or you could use multiplication
50*1/16=3.125gallons
The system of equations that represent the cost of x shirts, and y pairs of pants are 4x + 3y = 85.50 and 3x + 5y = 115.00. Option (a) is correct.
A system of equations or an equation system is a collection of simultaneous equations.
Given that Shopping at Saver Mart, Lisa buys her children four shirts and three pairs of pants for $85.50 and She returns the next day and buys three shirts and five pairs of pants for $115.00
Now we have to find the system of equation
Lisa buys her children four shirts and three pairs of pants for $85.50 is given by
4x + 3y = 85.50
She buys three shirts and five pairs of pants for $115.00 is given by
3x + 5y = 115.00
Therefore the system of equations that represent the cost of x shirts, and y pairs of pants are
4x + 3y = 85.50 and 3x + 5y = 115.00

It has been given in the question that Mary's team had lost 30% of the total of 20 games. There has been no ties for this team. It is required to find the number of matches that Mary's team lost.
Total number of games played = 20
Percentage of games lost by Mary's team = 30%
Number of games lost by Mary's team = (30/100) * 20
= 3 * 2
= 6
So Mary's team lost 6 games in all. I hope this is the answer you were looking for. The process is easy once you understand the words of the problem.
