60 slices in 5 cheesecakes. So 1 cheesecake has 12 slices. So 8 cheesecakes will have 96 slices
When an object start to accelerates it changes its state of motion.
A=adult
c=children
total lumber=30
total number=adults+children
a+c=30
total cost=50
total cost=acost+ccost
acost=a times cost per adult=a times 3=3a
ccost=c times cost per child=c tiems 1=1c=c
total cost=3a+c
50=3a+c
equiaotn are
a+c=30
3a+c=50
multiplyu first by -1 and add
3a-a+c-c=50-30
2a=20
a=10
sub
10+c=30
c=20
answer is A
8000-600=7400
7400 would be the new altitude using simple subtraction.
