Answer:
Step-by-step explanation:
22. √125 is closer to √121 or 11
23. √23.5 is closer to √25 or 5
24. ∛59 is closer to ∛64 or 4 (cubed)
(4 cubed = 64, 3 cubed = 27)
25. ∛430 is closer to ∛512 or 8
(512 - 430 = 82
430- 343= 87)
26. y² = 55 is equal to y = √55, Closer to √49 or 7
27. d² = 95 is equal to d = √95, Closer to √100 or 10
28. p² = 6.8 is equal to p = √6.8, Closer to √9 or 3
29. ∛210 is closer to ∛216 or 6 (cubed)
30. ∛520 is closer to ∛512 or 8 (cubed)
The answer is
15m^2n + 4/n
Hope that helps, have a nice night or day <4
Answer=7:13
Kenny's Weight*6/7=Melvin's Weight
So, for example, if Melvin's weigh was 7...
Kenny's Weight*6/7=7
divide both sides by 6/7
Kenny Weight=6
So we can say that Melvin's weight to Kenny's weight is 7:6
The boys total weights would be...
7+6=13
So Melvin's weight over the total weight of the two boys is:
7:13
I had that question yesterday
Answer:
Su=10
Explaination:
So from s to u on the nunebr line is worth 2x-12. So what is s to u worth? Well. S to t on the number line = x-7. T to u =6. And 2 x is worth 12 more than s to u, using th e expression. X has to be at least 8 because otherwise the x-7 wouldn't work, and u might get s to u = 0 or a negative number.
Say x was 13, then 13 - 7 =6. So S to t =6. And r to u =6. So s to u =12. (6+6). Then check if the expression fits this answer of 12. 2x - 12. 2x = 26. 26-12=14, which doesn't match.
Let's try 14. 14-7=7. Then s to u = 7+6=13. The expression: 2x= 28. 28-12=16. 13 and 16 dont match. So we have got further away from what we need. Why don't we try going in the opposite direction. Rather than testing 13 and +1, let's now - 1 and try 12.
If x=12, then s to t =12-7=5. And s to u =6+5=11. The expression: 2x=24.-12=12. We are very close now with 11 and 12.
Lets test x=11!
S to t = 11-7=4. 4+6=10. So s to u =10.
2x=22. 22-12=10. So the expression works and the number line measurements.
The answer is su=10 and x=11.
