Answer:
-27/5 and 29
Step-by-step explanation:
First, simplify everything. You get 20x - _ * 5/9 + 9x = 3 + _ * x.
This is 29x - _ * 5/9 = 3 + _ * x.
The 2nd blank must be 29 because there is nothing else to alter it.
Using the same logic, the first blank is -27/5.
First you have to multiply both sides by -5 which means you will multiply -5 by 6, -5 by k/5, and -5 by 9... So it should look like: -5×6+-5×k/5=-5+9.. after that.. it should look like -40+k=-45.. because the 5's in k/5 cancel out.. so then it should now look like k=-45+30... you subtract.. and k=-15
I did this in middle school i think they dialated it up by like 2
Let the numbers be 1k, 2k , and 3k respectively
Since the sum of their cubes is 4500,
(1k)³+(2k)³+(3k)³=4500
--> k³(36)= 4500
--> k = 5
Hence, the numbers are: 5,10 and 15 respectively
Answer:
