We could say that the number of pennies is 2x, nickels are 3x, and dimes are 4x. Adding all of them together, we get 2x+3x+4x=9x. We also know that 9x=1620 because the total amount of coins is 1620. Dividing by 9 on both sides we get x=180.
Pennies equal 2x= 2*180=360

Bryson buys a bag of 64 plastic miniature dinosaurs . could he distribute them equally into six storage containers and not have
MariettaO [177]
Okay so first you would ask your self does 64 divide by 6? So take out your calculator and divided 64 by 6. Doing so you find out the answer is 10.6 (repeating)
So each storage container would get 10? No that doesn't sound right, instead you have to turn the repeating 6 into a fraction so it would be each storage container gets 10 2/3 of a dinosaur.
