Explanation & Answer
Hey,Attached is some answers. Hope they aren't solved yet.
2) Solve the equation by clearing decimals first, and show the check of the answer:
4.75𝑛 − 3.5𝑛 = 4.4 + 0.8𝑛
Multiplying throughout by 100 we get
100 ∗ 4.75𝑛 − 100 ∗ 3.5𝑛 = 100 ∗ 4.4 + 100 ∗ 0.8𝑛
This becomes
475𝑛 − 350𝑛 = 440 + 80𝑛
This becomes
125𝑛 − 80𝑛 = 440
This becomes
45𝑛 = 440
This becomes
𝑛=
440
= 9.78
45
So n = 9.78
To crosscheck the value of n we will put value of n in above q...
