Answer:
Step-by-step explanation:
y is proportional to x when it satisfies the equation ...
y = kx
where k is the constant of proportionality. The equation can be solved for k by dividing by x:
k = y/x
The value of k for the given relation is ...
k = (320 mL)/(20 s)
k = 16 mL/s . . . the constant of proportionality
Then the equation is ...
y = 16x
Answer:
Yes
Step-by-step explanation:
I have had this question before.
X is cheeseburgers and y is hamburgers
x + y= 351
2x+y=351
Now I can do 351 divided by 3 which gives me 117. Since 117+117+117 is 351 and the number of cheeseburgers sold was twice the amount as hamburgers. I will say that there was 117+117 cheeseburgers sold and there were 117 hamburgers sold.
Hope it makes sense.....
Let's call that the Multiplicative Identity Property.
1 is the identity element for multiplication. Those are just fancy words for the obvious property that anything times 1 is itself.
21 + 20 = 43
Total is 123, so divide by 43.
123/43 = 2.86 rounded to 3.
