Answer:
9.5%
Step-by-step explanation:
To find out the percentage, you do (3.99/42) * 100.
So first y = 3.50 + 15 = 18.5
Next 2x + y = -1.5
2x = -1.5 -y
2x = -1.5 - 18.5 = -20
x = -20/2 = -10
So
x = -10
y = 18.5

Answer:
- Abel is 7 and Asare is 17 years old

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:
