The two coins chosen have to be a quarter and a penny. That leaves you with three pennies. You originally had 14 coins. You took out two you now have 12.

Answer:

B

Step-by-step explanation:

The 2 coins that have a combined value of 26 cents are a quarter and a penny. That means that 1 quarter and 1 penny must have already been removed from the bag. For this reason, the bag now contains 1 quarter, 5 dimes, 3 nickels, and 3 pennies. Therefore, the probability that a third coin randomly chosen from the bag will be a penny is

3

1 + 5 +3 + 3

=

3

12

=

1

4

Which equation represents a proportional relationship that has a constant of proportionality equal to -10
stira [4]

Answer:

y =  - 10x

Step-by-step explanation:

A proportional relationship has equation:

y = kx

where k is the constant of proportionality.

Since we are looking for a proportional relationship that has a constant of proportionality equal to -10, we have k=-10.

We substitute k=-10 into the equation to get:

y =  - 10x

Therefore the correct choice is

y =  - 10x
