7)
10x=y because y is 10 times larger than x.
a) Therefore y=1000 because we would multiply 100 by 10.
b) Again we must multiply be 10. So y=5000
8)
y=3x because y is 3 times larger than x.
a)
k=y/x
So y/x = 3
b) Since k=3, and each slice is 1/8 y. We can find the amount of cheese on each slice.
y/x=3
so y=3x
1/8 y = 3/8 x
