  • Tutorials are an optional student help tool available within select questions for just-in-time support. Students can use the tutorial to guide them through the problem-solving process step-by-step using different numbers.

Simplify.
3(1 + 8 · 6) − 82
Correct: Your answer is correct. seenKey

83


†

Solution or Explanation
The order of operations can be remembered using the acronym PEMDAS, where P stands for Parentheses, E stands for Exponents, MD stands for Multiplication and Division, and AS stands for Addition and Subtraction.
To simplify
3(1 + 8 · 6) − 82,
 the expression within the grouping symbols must be simplified first. Note that both multiplication and addition are within the parentheses, and multiplication must be performed before addition.
3(1 + 8 · 6) − 82 = 3(1 + 48) − 82
 = 3(49) − 82
The next step is to simplify any exponents.
3(49) − 82 = 3(49) − 64
In the expression
3(49) − 64,
 the
3(49)
 means that 3 is multiplied by 49, and since multiplication precedes subtraction in the order of operations, the expression
3(49) − 64
 simplifies as follows.
3(49) − 64 = 147 − 64 = 83
Hence,
3(1 + 8 · 6) − 82 = 83.

  • Responsive Questions personalize the learning experience by asking students to use their own real data, which provides the variables needed to answer each question part.

  • Part 1

    How can I predict how long it will take me to travel a nature trail?
    Use some information about a path or trail that you have previously traveled to predict your rate of travel. Recall that distance traveled is equal to the product of the rate of travel and the time:
    d = rt.
    The values you enter in this part will be used to make later calculations.
    Consider a path or trail that you have traveled before.
    How long is this path in miles?
    Correct: Your answer is correct. seenKey

    5

         Your value is acceptable. mi
    How long, in hours, does it take you to travel this path from beginning to end?
    Correct: Your answer is correct. seenKey

    3

         Your value is acceptable. hr

  • Part 2

    Use the values you entered in part 1 to determine the answer in this part.
    Use the equation
    d = rt
     to determine your rate of travel, in miles per hour, on this path. (Round your answer to the nearest tenth.)
    Correct: Your answer is correct. seenKey

    1.7

         mph

  • Part 3

    Continue investigating this situation.
    Use the rate you found in part 2 and the equation
    d = rt
     to determine how long it would take you, in hours, to travel each of the trails below. (Round your answers to the nearest tenth.)
    Trail Name Distance Time (in hours)
    Matadero Creek Trail 1.5 miles hr
    WestCliff Drive Trail 3.4 miles hr
    Sabercat Creek Trail 11.2 miles hr
