In a piggy bank on his dresser, Tom has a total of $2.85 in pennies and quarters. If the number of pennies is 5 more than three times the number of quarters, how many pennies
and quarters does he have in his piggy bank?

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

a

step-by-step explanation:

wow ok so the answer is 1k or just k

because of combining like terms xd

hi there!

not proportional because the 42 does not go into 120 and 3 does not go into 8.

correct proportion: $40/1 ticket.

the reason i say this is because 40/1 is simplified and it evenly goes into 120/3.

hope this : )
