sveta [45]

Answer: there are 8 quarters in the jar

Step-by-step explanation:

Let x represent the number of nickels that is inside the jar.

The total number of coins inside the jar is 20.

Probability is expressed as

Number of possible or favorable outcomes/total number of outcomes.

The probability of selecting a nickel is 0.6. This is expressed as

0.6 = x/20

Cross multiplying, it becomes

x = 20 × 0.6

x = 12

Since there are 12 nickels inside the jar, then the number of quarters would be

20 - 12 = 8

Please help with A,B for 10 points.
denis-greek [22]

Answer:

y= (C -Ax)/B

x= (C -By)/A

Step-by-step explanation:

Ax+ By = C

solve for y

Subtract AX from each side

Ax+ By - Ax = C-Ax

By = C -Ax

Divide by B

By /B= (C -Ax)/B

y= (C -Ax)/B

solve for x

Subtract By from each side

Ax+ By - By = C-By

Ax = C -By

Divide by A

Ax/A= (C -By)/A

x= (C -By)/A
