Step-by-step explanation:
Answer:
20
Step-by-step explanation:
0 to 1 = a difference of 1
1 to 2 = a difference of 2-1 = 1
===============
2 to 4 = a difference of 2
4 to 6 = a difference of 2
===============
6 to 9 = a difference of 3
9 to 12 = a difference of 3
===============
12 to 16 = a difference of 4
16 to 20 = a difference of 4
Answer:
The answer would bw A.10.47
52.34/1×20/100=10.47
let's say "x" is how old he will be in 2016, so in 2010, 6 years earlier, he's 4/5 ths of that age in 2016, or namely in 2010 he's (4/5)x. Since we know his total age in 2016 is "x", then if we just add 6 more years to (4/5)x, we'll get his age in 2016, or

4. x^2 = 49 so x = +/- 7
5. 3x^2 = 27
x^2 = 9
x = +- 3
6.x^2 = 225
x = +/- 15
