Answers

Answer: P(blue)=1/5. P(yellow)=2/5.

Step-by-step explanation: First find the total number of marbles. 4+1+2+3=10. To find the probability of blue marbles, use this equation (number of blue marbles (2) / total number of marbles(10) ). 2/10=1/5.

To find the probability of yellow marbles do this equation (number of yellow marbles (4) / total number of marbles (10) ). 4/10=2/5.

Express x in terms of a and b: b−7x=a−b

Answers

b - 7x = a - b
Subtract b from both sides.

-7x = a - 2b
Divide both sides by -7.

x = $(-a + 2b)/(7)$
