Leo’s basketball team makes 16 points in the first game, 22 points in the second game, and 18 points points in the third game. use the associative property of addition to show two different ways leo can group the addends to show the total number of points

we know that

The associative property of addition says that changing the grouping of the addends does not change the sum

in this problem

we have

(16+22+18)=56

First way

(16+22)+18

Remember that parentheses tell us to do something first

=(38)+18

=56

Second way

16+(22+18)

Remember that parentheses tell us to do something first

=16+(40)

=56

Notice that both ways sum 56

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
