Apiggy bank at the flea market has 5 more than double the number of dimes than quarters. the money in the piggy bank is worth $7.70. how many dimes and quarters are in the piggy bank?

Let d represents the dimes and q represents the quarters.

As per the statement:

A piggy bank at the flea market has 5 more than double the number of Dimes than quarters.

⇒q = 2d +5       ......[1]

It is also given that: The money in the piggy bank is worth $7.70.

⇒        ......[2]

Substitute equation [1] into [2] we have;

Combine like terms;

Subtract 5 from both sides we get;

Divide both sides by 3 we get;

Substitute the values of d in equation in [1] we get;

q = 2(0.90) +5 = 1.80 + 5 = $6.80

Therefore, the dimes and quarters are in the piggy bank is $0.90 and $6.80

step-by-step explanation:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
