Your friend shows you a coin collection. In it, StartFraction 32 Over 50 EndFraction of the coins are quarters. What percent of the coins are quarters?

The percent of the coins are​ quarters = 64%.

Step-by-step explanation:

According to the given question , we have

The fraction of coins are quarters in the coin collection  =

We know that to convert a fraction into percent , we multiply it by 100 .

Then , the percent of the coins are​ quarters =

which is equal to

Therefore , the percent of the coins are​ quarters = 64%.

Equation for length:
L=3w-35

By inputting this into the equation to find the perimeter we get:
2(3w-35)+2w=190
Distribute
6w-70+2w=190
Add like terms
8w=260
Divide both sides by 8
w=32.5
The width is 32.5cm

To find the length input w into the equation for length
L=3(32.5)-35
L=97.5-35
L=62.5
The length is 62.5cm

Check that the solution is correct by inputting the solutions to the perimeter equation

2L+2w=190
2(62.5)+2(32.5)=190
125+65=190
190=190

I hope this helps :)
