500x+0.04=y
400x+0.05=y
for percentages move decimal to the left twice
Answer: C (110)
reasoning: 50 times 2 = 100. 100 + 10 = 110
The value of n from the given expression is 5.5
<h3>Solution to linear equation and fractions</h3>
Fractions are expression written as a ratio of two integers. The linear equation on the other hand has a leading degree of 1.
Given the equation below;
n/11 = 3.5/7
Simplify to have
n/11 = 1/2
Cross multiply the given result to have:
11 = 2n
Swap
2n = 11
Divide both sides by 2 to have;
2n/2 = 11/2
n = 5.5
Hence the value of n from the given expression is 5.5
