D is the answer
(4+8)+1 = 13
4+(8+1) = 13
Therefore equation D is true
I got 11.5 lol I don’t really know why
9.4 because the number after the firs decimal point is higher than 5
We know that the total volume of the solution is 187 cubic feet.
187=3x+8x
187=11x
17=x
Now we know that the ratio 3 to 8 is 51 to 136.
Double check, (3*17)+(8*17)=187.
I'm not sure which part of the ratio is water, but knowing this information, you should be able to solve it. I believe it may be this:
The total volume of milk is 51. If the rest of the solution is water, then 187-51=136.
Answer:
230
Step-by-step explanation:
This year: 319 total; 33 unpopular
Last year: 394 total; 197 unpopular
Total songs over both years 319 + 394 = 713
Total unpopular over both years 713 - 483 = 230
