Ariana has a dimes and y nickels. She has at most 12 coins worth a minimum of $0.85 combined. Solve this system of inequalities graphically and determine one
possible solution.
PLEASE HELP

Solution graph is attached in the answer area.

And one possible solution is (9, 2).

9 number of dimes and 2 number of nickels.

Step-by-step explanation:

Given that:

Number of dimes =

Number of nickels =

Total number of coins are at most 12 OR total number of coins are lesser than or equal to 12.

i.e. the inequality can be written as:

...... (1)

One dime is worth 10 cents or $0.10.

number of dimes are worth $0.10.

One nickel is worth 5 cents or $0.05.

number of nickels are worth $0.05.

Second inequality can be written as:

OR

...... (2)

...... (3)

When we graphically represent the inequalities, the graph attached in the answer area represents the answer.

One solution is (9, 2).

9 number of dimes and 2 number of nickels.

i am thinking c. sorry if im wrong .

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
