You create a new type of food, and 60 of your friends tried it and shared if they liked it or not. Luke said he ratio of the number of people who liked the food to the number of people who did not like the food is 45:15. Melvin said that for every 3 people who liked the food, one person did not. Do Luke and Melvin agree?

Yes, they agree

Step-by-step explanation:

If 60 people tried the food ,

the ratio of people who liked the food = × 60 = 45

he ratio of people who did not like the food = 60 - 45 = 15

ratio of people who liked the food to those who didn't = 45: 15

dividing both sides by 15 = 3 : 1

So Luke and Melvin agree

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
