200 = x or x=200
i hope its right :)
Step-by-step explanation:
120 + 0.5x = 60 + 0.8x
-60 -60
60 + 0.5x = 0.8x
-0.5x -0.5x
<u>60</u>= <u>0.3x</u>
0.3 0.3
200 = x
I'm not sure what the 40 is in the problem, but if 43 students brought in 25 labels each, then 43x25= 1075 labels total were brought in altogether.
If the ratio of boys to girls in a class is 8:5 you will not be able to tell how many students are in the class because there could be 8 boys and 5 girls in the class or there could be 16 boys and 10 girls.
