Question

hiking the table shows the lengths of several trails tonya can take when she goes hiking
trail length (miles)
a 2.4
b 3.18
c 9.5
d 4.29
e 6.8
tonya hiked trail a five times, trail e three times, and trail c one time over the last month.
the expression \boxed{} (2.4) + \boxed{} (6.8) + \boxed{} could be used to determine the total length tonya hiked.
the total length is \boxed{} miles.

Explanation:

Step1: Identify multipliers for each trail

• Trail A: 5, Trail E: 3, Trail C: 1

Step2: Write the full expression

$$5(2.4) + 3(6.8) + 1(9.5)$$

Step3: Calculate each term

• $5(2.4) = 12$
• $3(6.8) = 20.4$
• $1(9.5) = 9.5$

Step4: Sum the terms

$$12 + 20.4 + 9.5 = 45.5$$

Answer:

5, 3, 1; 45.5 miles
