The answer is the first one
Step-by-step explanation:
y=kx
say that y is the original prince and x is the sale price
15=k(10)
15/10=k
3/2=k
you can check with the next problem to check if it is the same
25=k(20)
25/20=k
5/4=k
so you take 5/4-3/2=-1/4 so the constant is -1/4
Hope that helps :)
Answer:
9 cups
Step-by-step explanation:
If one pound is equal to 2 cups, then you would multiply 2 by 4, which gives you 8. If one pound equals 2 cups, then half a pound equals 1 cup. So since we already have 8 cups, you just add one more cup, which gives you 9 cups total
SUMMARY: You can expect to get 9 cups of grated parmesan cheese from a 4.5-pound block.
10 / 1/5 = 50
hope this helps!
2/15
90 ÷ 6 = 15
Theoretical probability would be 15 due to the equation above
