Leo has a bag of dimes and quarters. He has a total of 29 coins worth $4.70. Let x represent the number of dimes and y represent the number of quarters. Which system of equations would be used to find out how many dimes and quarters Leo has? {x+y=290.1x+0.25y=4.7

{y=x+29x+y=4.7

{x=29−yx+y=4.7

{x+y=4.70.1x+0.25y=29

(60 points)

x+y=29

0.1x+0.25y=4.7

Step-by-step explanation:

- x+y=29 (x is the number of dimes and y is the number of quarters. there is a total of 29 coins)

- Each dime is $0.1 and each quarter is $0.25.

- By multiplying the number of dimes by $0.1 and multiplying the number of quarters by $0.25, you will get the total amount of money, which is $4.7. - - Therefore, the answer is:

x+y=29

0.1x+0.25y=4.7

Hope this helps! :) I also took the K12 quiz, here is proof that this is right:

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
