@Rolexflex1 I don't have have an account, but have experience on AI Annotations. I've worked on Outlier accounts and I am interested in working with you Sir
@Beno10_MFC Left side Scale: 5 red balls + 2 kg
Right side Scale: 3 red balls + 7 kg
Hence,
5R + 2kg = 3R + 7kg
Now, solve for R
(5 - 3)R = (7 - 2)kg
2R = 5kg
Divide both sides by 2
2R/2 = 5kg/2
R = 2.5kg
Therefore, each Red ball weighs 2.5kg
Check follow up comment for proof solving
@147annu_ First, we find the value of n
6n - n = 30
5n = 30
Divide both sides by 5
5n/5 = 30/5
n = 6
Note: n = 6
Hence, 3n = x
3(6) = x
18 = x (3n = 18)
PROOF
6(6) -6 = 30
36 - 6 = 30
30 = 30

Thank you!!! πβπΎ
@Im___maryam In order to get the true value of r, we have to find the half of 98; cause a half of 98 will equal an rΒ²
SOLVONG FOR THE R.H.S TO GET r
Hence,
98/2 = 49
Take the square root
β49 = 7
Note; r = 7
So,
7Β² + 7Β² = 98
49 + 49 =98
98 = 98

@Hadiyorumla In continuation
When a = -6, then;
-6 + b = 36
Now, add 6 to both sides
-6 + 6 + b = 36 +6
b = 42
Note: a = -6 & b = 42, then;
b/a = 42/-6
= -7
Hence, when a is -6, then b/a = -7
Thank you!!! πβπΎ
@Hadiyorumla SOLVING
aΒ² = 36
Check for the Square roots
β(a)Β² = β36
a = +-6
When a = 6, then;
6 + b = 36
Now, subtract 6 from both sides
6 - 6 + b = 36 - 6
b = 30
Note: a = 6 & b = 30, then;
b/a = 30/6
= 5
Hence, when a is 6, then b/a = 5
When a = -6, then;
Check the next comment..
@RHSTUDYZONE But note:
(βM)Β² = β100
M = +- 10
So, if M = -10, then;
M + 4 = x
-10 + 4 = x
Hence, x = -6
If M = 10, then;
M + 4 = x
10 + 4 = x
Hence, x = 14
Therefore, x is - 6 or 14
I couldn't put all the solving cause of X limit on comments
Thank you!!! πβπΎ
@RHSTUDYZONE First, we find the value of M
MΒ² / 4 = 25
Cross multiply
MΒ² = 4(25)
MΒ² = 100
Now, take the square root
(βM)Β² = β100
M = 10
Since M = 10, then;
M + 4 = x (unknown)
10 + 4 = x
14 = x
x = 14
PROOF
(10)Β² / 4 = 25
100/4 = 25
25 = 25

@zaini875u Let i= 1 & k = 1;
(50 + i + k) - 30 = x
But the values of i and k are both 1
Hence,
(50 + 1 + 1) - 30 = x
USING BODMAS/BEDMAS
52 - 30 = x
22 = x
x = 22
Therefore, the total number of people left in the room are 22 inclusive with you, and the killer π₯²
Thank you!!! πβπΎ
