Answer:
x> y-300/12
Step-by-step explanation
1. Subtract 300 from both sides
2. Divide both sides by -12
3. Switch the sides
The years when the Russo-Japanese war had not yet happened is the year of 1903 and before
Let x represents years, the inequality system is x < 1904
This is simply a question about ratios. This ratio means that for every 1 cm on the map, there are 12 km in actuality. You can set this problem up in fractions:
1 cm 12 cm
-------- = ----------
12 km x
To solve for x, we cross-multiply, for the moment ignoring units. Remember, your answer will be in km.
1*x=12*12
x=144
If x=144, then for 12 cm, there are 144 km.
Answer:
Set the two equations equal to each other if you want me to solve tell me.
So.... 15x+10=16x+3
-15 -15
10=1x+3
-3
7=x
