Answer:
That is a correct statement.
Step-by-step explanation:
This is because to find the appropriate amount, we would multiply the two numbers together. Since we are multiplying 4.15 by a number less than 1 (0.8), the number can only be lower. The number would only be higher if the number was greater than 1.

Step-by-step explanation:
7(5x+12)=2x-3
=35x+84=2x-3
=35x-2x=-3-84
=33x=-87
then divide both side by 33
Answer:
21/70=x/30
Step-by-step explanation:
Noticing that it is referring to problem b, we head over to that. It states two important pieces of information. Only seventy percent of the players participated, and 21 total played. This means we can simply divide 21 by 7, and multiply by 10. This shows us that there are thirty total players because 21/7 is equal to 3, multiplied by 10 is equal to thirty. 30 minus 21 is equivalent to 9, meaning 9 players did not play. The proportion we would use for this is 21:70 equal to x:30. Cross-multiply, and we get 70x = 630. x = 9, thus proving our answer is correct.
