Multiply the mantissas: 4.2 x 3.7 = 15.54, add the exponents 5+6= 11 so 15.54 x 10^11, BUT WAIT, there can only be one digit in from to the decimal, so 1.554 x 10^12 (add 11 + 1 decimal place change, so 12)

PLEASE HELP

Mandarinka [93]

Let x=large boxes and y=small boxes.

x+y=110

60x+35y=5100

____________

You need to cancel out one of the variables to solve for one. Let's cancel out y.

-35(x+y=110)

-35x-35y=-3850

60x+35y=5100

____________

Add the two equations.

25x=1250

x=50

_____________

Plug in 50 for x into one of the equations to solve for y.

50+y=110

y=60

_____________

50 large boxes

60 small boxes
