  • Q #1: James’ uncle is thirteen less than three times James’ age. Which of the equations represents James’ uncle’s age (m) as it relates to James’ (n)?

    A. m=13-3n

    B. n=3m-13

    C. m=13-3n

    D. m=3n-13

    Answer Explanation

    in this case, we express James’ uncle’s age in terms of James’ age. From the equation:

    James’ age is n

    James’s uncle’s age is m=3n-13

    Thus, the relation that relates James’ uncle’s age in terms of James’ age is m=3n-13.

  • Q #2: A child has a bottle full of pennies, nickels, dimes, and quarters. There are four as many quarters as pennies, two times as many as nickels as pennies, and seven times as many dimes as nickels. How many more dimes does the child have than nickels?

    A. 7 times as many

    B. 5 times as many

    C. 2 times as many

    D. 10 times as many

    Answer Explanation

    This problem asks us to compare the number of dimes to nickels.

    If we let p be number of pennies in the bottle. Then,

    Number of quarters in the bottle = 4p

    Number of nickels in the bottle = 2p

    Number of dimes in the bottle =7(2p)=14p

    To find the number of dimes the child has than nickels, we use the ratio:

    \(\frac{Dimes}{nickels} =\frac {14p}{2p}\ =\ 7\)

    Thus, there are 7 times as many dimes as nickels in the box.

    C. 121 lb

    D. 242 lb

    Answer Explanation

    We are asked to convert kg to pounds using the given relation. If we let x to represent the lb we are asked to find, we set the proportion equation with kg on numerator and lb on the denominator as follows.

    The equivalent value of 55kg is 121 lb.
