Answer: x = 9, 5

<u>Step-by-step explanation:</u>

4 | x - 7 | + 2 | x - 7 | = 12

6 | x - 7 | = 12      <em>added like terms</em>

  | x - 7 | = 2       <em>divided both sides by 6</em>

x - 7 = 2         or         x - 7 = -2     <em>removed absolute value sign</em>

    x = 9         or               x = 5     <em>added 7 to both sides of both equations</em>

Answer: explanation

Step-by-step explanation:

1. answer:2592

explanation: it says to find the % of the small sample so 45 out of 75 is 60% then says to convert it into a decimal and multiply it by 4,320 which equals 2592.

2. answer:

explanation:540 is 12% of 4500. I don't quite understand what that number is but I'm assuming it's the percentage number and that number is 12 and that's 12% out of 100. if it means what percentage 540 is out of 100 then its 540%

3. answer:30
explanation: 4 out of 20 is 20% converted to decimal is 0.2 then multiply it by 15 0 and that adds to 30.

Answer:

x = 45

Step-by-step explanation:

→ Add all the angles together

x + 2x + 3x + 90 = 360

→ Simplify

6x + 90 = 360

→ Minus 90 from both

6x = 270

→ Divide by 6

x = 45
