Jim has a total of 12 coins. some of them are nickels, and the others are quarters. if he had 12 more nickels, then the value of the nickels would be the same as the value of the quarters. how many quarters does he have?
let n = the number of nickels and q = the number of quarters.
which two equations can be used to solve this problem? select the two that apply.

i dont know if you cant find a way its best to actually add all of them start from 105 tho

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
