Answer:
-49/3 and -25/3
Step-by-step explanation:
Let the numbers be represented by f and s (first and second). Then f = s - 8. Also, 2f = 3s + 9. Solve this system for f and s:
Substituting s - 8 for f in the 2nd equation, above, yields
2(s - 8) = 3s + 9, or 2s - 16 = 3s + 9. Then 3s = -25, and s = -25/3. The first number is then f = s - 8, or f = -25/3 - 8, or f = -49/3.
Answer:
x>6
Step-by-step explanation:
-3x<-18
3x>18
Therefore, x>6
Answer is A) y=6x
Recall that a proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if ,
y=kx
Where k is a constant number.

Answer:
About 11.10 if it is 315. However it is about 10.95 if it is 313
Step-by-step explanation:
I believe the answer is 21.23 kilograms.
Explanation
You take 52 and divide by 5 because you’re trying to figure out for the whole year. Then you take what 52 divided by 5 is and multiply by 4.5 since he buys 4.5 pounds every 5 weeks. Then you convert that number which is 46.8 into kilograms which gives you 21.22812
