Initial Knowledge Check Question 9
On Wednesday, a local hamburger shop sold a combined total of 243 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the
number of hamburgers sold. How many hamburgers were sold on Wednesday?

Step-by-step explanation:

Let x=hamburger and y=cheeseburger

243=x+y

Y=2x

Plug second equation into first one

243=x+2x

243=3x

Divide each side by 3

61=x

So 61 hamburgers and 122 cheeseburgers (plugging x into second equation)

22 dimes and 9 nickels

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
