Question

Find the value of t perimeter

Answer 1

Answer:

t = 15.2 is the answer

Step-by-step explanation:

1. Make an equation

numbers to find perimeter = perimeter

Side + Side + 2 unknown sides = perimeter

12 + 7.8 + 2t = 50.2

2. Simplify like terms

19.8 + 2t = 50.2

3. Solve

19.8 + 2t = 50.2

-19.8        - 19.8

2t = 30.4

t = 15.2

4. Check:

12 + 7.8 + t + t = 50.2

12 + 7.8 + (15.2) + (15.2) = 50.2

50.2 = 50.2   Correct!

Answer 2

Answer:

t = 15.2 miles

Step-by-step explanation:

First, let's add the top and bottom numbers together.

7.8 + 12 = 19.8 mi

Next, we subtract that from 50.2 to get the combined value of both t's.

50.2 - 19.8 = 30.4 mi

Finally, we can divide 30.4 by 2 to get the value of t.

30.4 ÷ 2 = 15.2 mi

To check our answer, we can add all the sides up to see if they equal to 50.2. 15.2 + 15.2 = 30.4

30.4 + 12 + 7.8 = 50.2
