With the introduction of decimals, Max is very confused about the role zeros play in a number. For example 3 and 30 are not equal, but 3 and 03 are. Similarly 0.3 and .3 are equal, 0.3 and 0.30 are equal, but 0.3 and 0.03 are not. Explain to Max when and why introducing zeros a↵ects the value of the number.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
