1: the value of -3 xy , for x = 2 and y = 3, is -18.

true or false

2: the value of x 3y , for x = -2 and y = 3, is -24.

true or false

number machines=100=10² machines.

number pages/1 machine=10⁴ pages/ machine.

number pages that can print 100 machines in a day=

=10² machines * 10⁴ pages/ machines=10²⁺⁴ pages=10⁶ pages/day.

necessary days to print 10⁶ pages=number pages/ number pages that can print 100 machines in a day.

necessarry days to print 10⁶ pages=10⁶ pages / 10 ⁶ pages/day=10⁶⁻⁶ days=

=10⁰ days=1 day.

1 day for print 10⁶ pages, whith 100 machines.
