To solve the set of equations given above, we can use the substitution method where we substitute one equation to the other and solving for one variable. We do as follows:
<span>0.4x - 0.1y = 2
x = 5 + 0.25y
0.2x + 0.5y = 1
</span>0.2(5 + 0.25y)+ 0.5y = 1
y = 0
x = 5
Therefore, the correct answer from the choices is option A, (5,0).
Answer:
The answer top your question is: 1/2, 3/2, 5/2 and 7/2
Step-by-step explanation:
Data
4 consecutive numbers that add up to 8
First number = n
2nd number = n + 1
3rd number = n + 2
4th number = n + 3
Now, add them up n + n + 1 + n + 2 + n + 3 = 8
Simplify like terms
4n + 6 = 8
4n = 8 - 6
4n = 2
n = 2/4 = 1/2
First number = n = 1/2
2nd number = n + 1 = 1/2 + 1 = 3/2
3rd number = n + 2 = 1/2 + 2 = 5/2
4th number = n + 3 = 1/2 + 3 = 7/2
