Equality Properties
Step-by-step explanation:
<u>Step 1: Define</u>
4x - 12 ≤ 16 + 8x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 4x on both sides: -12 ≤ 16 + 4x
- Subtract 16 on both sides: -28 ≤ 4x
- Divide 4 on both sides: -7 ≤ x
- Rewrite: x ≥ -7
Here we see that any value <em>x</em> greater than or equal to -7 would work as a solution to the inequality.
∴ our answer is -7.
Just remember that 1 mile is equal to 5,280 feet.
If we have 5 miles, we need to multiply it my 5,280 which would equal 26,400.
Then we have the other 529 feet that they gave. Just add 26,400ft and 529ft and they will equal 26,929 ft.
Hope it helped! Remember, five tomatoes! (five two eight oh(0)).
