340 mm, 0.34 m. this is a case of division, in where you divide by 100. examples come from this question. 720 divided by 100 is 7.2 and 1256 divided by 100 is 12.56. i hope this helps in a way
Your ultimate goal is to get the variable secluded all by itself. You'll have to use the opposite operation to do this and remember, what you do to one side, you have to do to the other.
1. 9s + 3 = 57
2. Subtract 3 from each side. This will result in 9s = 54
3. To undo the multiplication of 9s you'll divide both sides by 9. 9s/9 = 54/9
4. The ending result is: s=6
5. Go back and check your work by substituting it in your original equation.
Answer:
12 = 5 + x
Step-by-step explanation:
Total fish in the aquarium = 12
Number of guppies fish = 5
Number of other fishes = x
Total fish in the aquarium = Number of guppies fish + Number of other fishes
12 = 5 + x
Subtract 5 from both sides
12 - 5 = 5 + x - 5
7 = x
x = 7
Number of other fishes = x = 7
It has to be the last one, D. I did it over 3 times to make sure.
