Answer:
- Abel is 7 and Asare is 17 years old
Step-by-step explanation:
Let the age of Abel is x and age of Asare is y.
Three times the age of Abel is four more than the age of Asare:
And
In three years, the sum of their ages will be 30 years:
We got two equations.
Simplify and solve by substitution:
- 3x - 4 + x = 24 Substitute y
- 4x - 4 = 24
- 4x = 28
- x = 7
Find y:
Apply distributive property
(5x+6)-(2x-3)
=5x+6-2x+3 arrange like terms
Simplify =5x-2x+6+3
Equals 3x+9 final answer
Answer:
C. I and III

Si en la pantalla aparecen esos numeros entonces tenes que hacer alguna calculacion para que aparezcan los siguentes numeros indicados. Para cada opcion necesitas apretar las sigientes teclas que aparacen en negro...
0.572 - 0.447 = 0.125
0.572 - 0.194 = 0.378
0.572 + 0.307 = 0.879
0.572 - 0.116 = 0.456
0.572 + 0.428 = 1
