Victor has a bag of dimes and quarters. He has a total of 36 coins worth $5.40. 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 Victor has?

{x+y= 5.4
0.1x +0.25y =36

{x=36−y
x+y=5.4

{y=x+36
x+y=5.4

{x+y=36
0.1x+0.25y=5.4

{x+y=36

0.1x+0.25y=5.4

Step-by-step explanation:

just took the test sorry for being late

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
