Hi guys really need help w/ this problem will give brainllest for the first person
Vladimir [108]

Answer:

There are 6 nickels, 10 dimes and 13 quarters.

Step-by-step explanation:

number of nickels = n

number of dimes = n+4

number of quarters = (n+4)+3 = n+7

express total amount in cents $4.55 = 455 cents

express total in cents by multiplying quantities of coins by value and adding them up.

455 = 5*n + 10*(n+4) + 25*(n+7) 455 = 5n + 10n + 40 + 25n + 175 240 = 40n n = 6

so number of nickels = 6.

number of dimes = number of nickels + 4 = 6+4 =10

number of quarters = number of dimes + 3 = 10+3 = 13

There are 6 nickels, 10 dimes and 13 quarters.

Do the ratios 4/2 and 10/5 form a proportion? Yes or no
mars1129 [50]

Answer:

These are both 20 so that means that this is proportional, yes.

Step-by-step explanation:

Hi.

To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.

Here is how we do this.

\frac{4}{2}    \frac{10}{5}

So basically what we are doing is multiplying across in a diagonal direction.

Diagonal meaning like a slash / .

So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.

Do the same for the 2 and the 10.

So we have to multiply :

4 x 5

2 x 10

=

20

These are both 20 so that means that this is proportional, yes.

Hope this helps.

If you have any questions or concerns feel free to message me.
