James has a jar full of just pennies and nickels. The ratio of pennies to nickels is 8 to 3. Which of the following is the ratio of nickels to the number of all the coins? (1) 3 to 11 (3) 3 to 8
(2) 5 to 8 (4) 8 to 11

(1) 3 to 11

Step-by-step explanation:

Ratio of pennies to nickels is 8 to 3.

Pennies : nickels = 8 : 3

Pennies = 8

Nickels = 3

Total coins = pennies + nickels

= 8 + 3

= 11

Which of the following is the ratio of nickels to the number of all the coins?

Nickels : Total coins = 3 : 11

Or

= 3 / 11

Or

3 to 11

The correct answer is (1) 3 to 11

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
