Step-by-step explanation:
The answer is 700 meters
why?
1. km=1000.m so when you move the 1 to the right .1 you have to do the same woth 1000. which will be 100.0

why?
1 quart=4 cup so change 1 to 5 which means *5 and the same with cups 4 to 20 which means *20

Step-by-step explanation:
<u>Step 1: Define</u>
9(2x + 1) < 9x - 18
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 9: 18x + 9 < 9x - 18
- Isolate <em>x</em> terms: 9x + 9 < -18
- Isolate <em>x</em> term: 9x < -27
- Isolate <em>x</em>: x < -3
Here we see any value <em>x</em> smaller than -3 would work as a solution to the inequality.
False because for example using order of operation:
3-4*2= -5
But not using order of operation:
3-4*2=-1
