Answer:
Yes, it is directly proportional.
Step-by-step explanation:
Since Anna does a sit-up at a certain amount of time, then we have two quantities we are comparing: a sit up and the amount of time it takes.
It is said that the tired she gets, the more time she uses. Therefore, as her tiredness increases, the amount of time also increases. This implies that the quantities are proportional, directly proportional.
The answer will be A. Hope it help!
5x+2y=9
-3x-2y=-7
The +2y and -2y eliminate
2x=2
x=1

Step-by-step explanation:
We are given that
Priya uses flour to make 3 loaves of bread= 7 1/2 = 15/2 cups
Andre uses b loaves of bread using flour=f cups
We have to find the relationship between b and f.
When both recipes are same then ratio of flour to the loaves of bread remains same in both recipes.
To find the relationship between b and f we will find the ratio of flour to the loaves of bread in Priya's recipe.
Therefore, ratio of flour to the loaves of bread in Andre's recipe
This is required relationship between b and f.
