Please check the explanation.
Step-by-step explanation:
<u>Determining equation B from Equation A</u>
Given the equation A
Apply distributive law 
which is equation B
Hence, equation B can be obtained by implementing the distributive law operation on equation A.
<u>Determining equation A from Equation B</u>
Given the equation B
Factor out common term -2 on the right-hand side of the equation
which is the equation A
Hence, equation A can be obtained by factoring out the common term -2 on the right-hand side of equation B.
The second one is the correct answer .
Answer: $53
Step-by-step explanation:
Given: Earning of Arthur in three weeks = $136

Hence, Arthur must earn $ 53 in the next week.
Answer:
1/6
Step-by-step explanation:
the probability of the red die shows a number larger than 3 (P1) = 3/6 = 1/2
the probability of the green die shows a number less than 3 (P2) = 2/6 = 1/3
the probability of both happening = P1 * P2 = (1/2) * (1/3) = 1/6
