Answer:
161.68°F to 182.32°F
Step-by-step explanation:
6%=6/100= 0.06
0.06×172=10.32°F
thus temperature range is
(172 + or - 10.32)°F

Step-by-step explanation:
<u>Step 1: Define</u>
5k + (-7) = 13
<u>Step 2: Solve for </u><em><u>k</u></em>
- Simplify equation: 5k - 7 = 13
- Addition Property of Equality: 5k - 7 + 7 = 13 + 7
- Simplify equation: 5k = 20
- Division Property of Equality: 5k/5 = 20/5
- Simplify equation: k = 4
<u>Step 3: Check</u>
<em>Plug in k into the original equation to verify it's a solution.</em>
- Substitute in <em>k</em>: 5(4) + (-7) = 13
- Multiply: 20 + (-7) = 13
- Add: 13 = 13
Here we see that 13 does indeed equal 13.
∴ k = 4 is the solution to the equation.
<h3>
Answer: 40 inches</h3>
==========================================================
Explanation:
- x = first piece
- 2x = second piece, since its twice as long as the first
- 5x = third piece, since its five time as long as the first
x is some positive real number, and the units of each are in inches.
Add up the smaller pieces and we should get 64 inches back again
x+2x+5x = 64
8x = 64
x = 64/8
x = 8
The first piece is 8 inches long.
2x = 2*8 = 16 is the length of the second piece (in inches)
The third piece is 40 inches because 5x = 5*8 = 40
--------
Summary:
first = 8 inches
second = 16 inches
third = 40 inches
Check: 8+16+40 = 64, which confirms the answer
