It's an identity if it has infinite solutions and everything is right, which would mean that if both sides of the equation are equal after eliminating the variable then the variable does not matter and it will always be equal. If it is not equal after eliminating the variable then that means that no matter what the variable is, it does not matter and the equation will have no solution

DedPeter [7]
1 quart is equal to 4 cups, so you divide 12.70 by 4.
12.70 \div 4 = 3.175
You can round that up to $3.18 for 1 cup of balsamic vinegar

Find the constant rate of change for the representation,<br><br> 24x-28y=14
dem82 [27]

Answer:

6/7

Step-by-step explanation:

The constant rate of change is also know as the slope of the expression

Given

24x-28y=14

Write in standard form y = mx+c

m is the slope

24x-28y=14

-28y = -24x + 14

y = -24x/-28 + 14/-28

y = 6/7 x - 1/2

Compare

mx = 6/7 x

m = 6/7

Hence the  constant rate of change is 6/7

Two cyclists start at the same point and travel in opposite directions. One cyclist travels 6 / km h faster than the other. If t
Alex17521 [72]
We can find the rate of each cyclist (assuming the rate is the amount they can travel in an hour)  by dividing by 4 and then adding 6.

216/4 = 54

54 + 6 = 60.

The rate of each cyclist is 54 km/h and 60 k/ph.
