Answer:
Noor's age is 12 & Salma's age is 18
Step-by-step explanation:
Noor's age: N
Salma's age: S
: given
: given
: isolate "N"
: substitute the value of N for N to find the value of "S"
: subtract 3 from both sides
≡ 
: multiply both sides by 2
: add like values
: divide both sides by 3
S = 18
now insert that value into the initial equation:
: subtract 18 from both sides
Answer: 24
Step-by-step explanation:
Solve for n.
0.2(n - 6) = 2.8
Distribute
0.2*n - 0.2*6 = 2.8
0.2n - 1.2 = 2.8
Now inverse operation should be applied
0.2n - 1.2 = 2.8
+ 1.2 +1.2
2.8 + 1.2 = 4
0.2n = 4
0.2n/0.2 = 4/0.2
n = 20
Answer: 20
32 is the outlier, cause it’s much bigger than the other numbers
