Answer:
23
Step-by-step explanation:
If Abel was born in 1994, in 2019 he would be 23.
1+9+9+4=23
1. 79% Take 100 x 21%=21, then subtract 21 from 100 = 79
2. $138 Take 1200 x 11.5%= $138
Answer:
Let x = the 2nd number
Let x + 8 = the first number
Let 4x = the third number
x + x + 8 + 4x = 122
6x + 8 = 122
6x = 114
x = 19
x + 8 = 19 + 8 = 27
4x = 4(19) = 76
Step-by-step explanation:
The sum of three numbers is 122 . The first number is 8 more than the second. The third number is 4 times the second
