Larson uses 2 tablespoons (tbsp) of oil for every 5 tablespoons of vinegar in a science experiment. He uses a total of 20 tablespoons of vinegar. The tape diagram below represents this situation. image 7ab5bfdf0ba844ca8e92c8aff1fdf52a

How many tablespoons of oil should Larson use?

8 tablespoons

Step-by-step explanation:

your ratio is 5:2 so for every 5 we will need 2. so 5 times what is 20. well 4 so now we need to multiply 2 by 4 to get 8 and your ratio becomes 20:8.

Sorry, I had done this wrong but I can't delete it. Look at  

sophiamilcheva's answer they did it correctly.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

make sure you have version 2.50

try looking in the very back of the book : )
