Answer:
Marla did 64 sit ups each day for one week = (60*7)+(4*7)= 448
Marla did 64 sit ups each day for one week =(50*7)+(14*7)= 448
Marla did 64 sit ups each day for one week =(40*7)+(24*7)= 448
Step-by-step explanation:
Marla did 64 sit ups each day for one week = 64 *7 = 448
A distributive property allows us to multiply a sum by multiplying each addend separately first and then summing the products together.
64 sit ups could be written as 60+4, 50+14 or 40+24.
Apply the distributive property:
Marla did 64 sit ups each day for one week = (60*7)+(4*7)= 448
Marla did 64 sit ups each day for one week =(50*7)+(14*7)= 448
Marla did 64 sit ups each day for one week =(40*7)+(24*7)= 448
We can try any two numbers whose sum is 64 and all will give us the answer 448....
