Answer:......................................................
Step-by-step explanation:
Walter will have walked 1.05 miles.
To find the missing piece on the right side, we need to set up and solve the following proportion.
0.2 / 0.5 = 0.3 / x
x = 0.75
Now, that we know the 2 pieces on the right side, just add them together.
0.3 + 0.75 = 1.05 miles

Let's find the critical points of the inequality.<span><span><span><span>

(<span><span>−x</span>+1</span>)</span><span>(<span>x+5</span>)</span></span>=0</span>(Factor left side of equation)<span><span><span><span>

Check intervals in between critical points. (Test values in the intervals to see if they work.)<span>

−5</span><x</span><1</span>(Works in original inequality)<span>
x>1</span>(Doesn't work in original inequality)
Answer: −5<x<1
Answer:
8x10^-6
Because the decimal point must be moved left 6 places in order to be equal when multiplied by the whole number the 10 must be to the -6th
