Answer:
x<5/2
Step-by-step explanation:
We have
2x−3<2
Add 3 to both sides.
2x−3 +3 <2 +3
which makes
2x<5
Divide both sides by 2.
2x/2 < 5/2
x<5/2
Answer:
28
Step-by-step explanation:
We will keep dividing by prime numbers until both are one (we will only consider whole divisions)
```
14 28 | 2
7 14 | 2
7 7 | 7
1 1
Now we <em>m</em><em>u</em><em>l</em><em>t</em><em>i</em><em>p</em><em>l</em><em>y</em> the left collumn, to get the LCM
2 * 2 * 7 = 28
And this was the vertical method, ok?
9.3*10 miles, which is 93,000,000 miles
