72-(63-8) and (72-63)-8

Answers

Answer 1

Answer: The Priority is always to parenthesis. It means that in both equations, begin by operating what's inside the parenthesis. Then Subtract what's left.

For the first one you get:
$72 - (63-8)$
$72 - 55$
$17$

For the second one you get:
$(72-63)-8$
$9-8$
$1$

Which mean that The 2 equations are not equal, because $17 \ \textgreater \ 1$
Hope this Helps! :D

Answer 2

Answer: They are not equal because for each you get different answer.

$72-(63-8) \n 72-55 \n 17$

$(72-63)-8 \n 9-8 \n 1$

17 and 1 are not equal.

Therefore, the two expressions 72-(63-8) and (72-63)-8 are not equal .

a travel company has 132 tourists who are going on a boat ride. each boat holds 8 passengers. how many boats does the travel company need to book ?

Answers

ok so
total capacity that all boats ordered can carry should be at least 132
total capacity that all boats ordered can carry =number of boats times number of people each boat can carry

people each boat can caryy=8 people
x=numbe of boats
132=x times 8
divide both sides by 8
132/8=x times 8/8
16.5=1x
16.5=x
you can't order 0.5 boats so round up to nearest whole
16.5 to 17

answer is 17 boats

132/8=16.5 boats
since you cant get 16.5 boats, round up to 17 boats.
