Anne bought 3 hats for $19.50. which equation could be used to find the cost of each equation?

19.50/3

Step-by-step explanation: if you have 19.50$ and you buy three separate things then you divide the 19.50 by 3. all you have to do is put your amount in the front (x) and afterwards put your amount of division in the back (y) like so X/Y

19.50x 3 or 19.50+19.50+19.50

Step-by-step explanation:

You could either multiply it or divide!

Hope I helped!!

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
