3 cm = 24 miles
2.5 cm = 20 miles
8 cm = 64 miles
12 cm = 96 miles
4.5 = 36 miles
To find miles and cm just use a multiplication chart of 8 and with the decimals, just multiply it with 8.
EX:
2.5 • 8 = 20
If j represent the number of jelly beans in each box, then the equation that models the problem is; 6j = 324
<h3>How to model an equation?</h3>
We are told that the principal used 6 small boxes of jelly beans to fill a large glass jar.
Now, each box had the same number of jelly beans, for a total of 324 jelly beans.
If j represent the number of jelly beans in each box, then the equation that models the problem is; 6j = 324
