EXPLANATION:
-To formulate an equation, you must first know what data the exercise gives us to locate them correctly.
data:
-6 that must be added to a number.
-four times a number that is equal to 4x
-a result that is equal to 50
Now with these data we formulate the equation:

if we solve the equation we have:
Answer:
The first one.
Step-by-step explanation:
When data values line up one way or another, whether the slope is positive or negative, the correlation will not be near zero. The graph you want is one that displays no particular trend.
This is what you’re looking for !
Part A
There are 2 cups in a pint, so 2 x 3 = 6
Plus 5 cups,
1 quart is equal to 1/4 of a gallon, and there are 4 cups in a gallon,
and another quart is 4 more cups,
so add all of the cups together:
6 + 5 + 4 + 4 = 19
Kelly is incorrect, because I added all of the cups together and I got 19.
Part B
Since 4 cups fit in a quart, and she has 4 quarts, her quarts only hold 16 cups, which isn't enough, because there are 19 cups.

Multiply your equation by the inverse of the coefficient of d to get d by itself.

With d on the left, this is
... d = r·t
