If 8x300=2,400, then 8x320 would equal 2,560. Why? Because 8x20=160. 2,400+160=2,560.
Hope this helps! :)
Group 1 elements are comprised of: (1) hydrogen, sodium, lithium, potassium, rubidium, caesium, and francium. The tendency of these atoms is to lose one of their electrons such that they become charge +1.
Group 5 elements contains the vanadium, niobium, tantalum, and dubnium. It is quite hard to predict the oxidation number of these elements such that it will be hard to determine the number of atoms needed to react with them. Their valence electron is 5, and they react by losing them. Hence, in order to reach the octet rule, 3 group 1 elements should be reacted.
Complete question :
A company has two manufacturing plants with daily production levels of 5x + 11 items and 2x - 3 items, respectively, where x represents a minimum quantity. The first plant produces how many more items daily than the second plant?
Answer:
3x + 14
Step-by-step explanation:
Given that:
Production level of plant 1 = 5x + 11
Production level of plant 2 = 2x - 3
The first plant produces how many more items daily than the second plant :
Plant 1 production - plant 2 production
(5x + 11) - (2x - 3)
Open the bracket :
5x + 11 - 2x + 3
5x - 2x + 11 + 3
3x + 14
Daily production of plant 1 exceeds that of plant 2 by 3x + 14

There are a few steps to follow when you add or subtract rational expressions with unlike denominators.
To add or subtract rational expressions with unlike denominators, first find the LCM of the denominator. The LCM of the denominators of fraction or rational expressions is also called least common denominator , or LCD.
Write each expression using the LCD. Make sure each term has the LCD as its denominator.
Add or subtract the numerators.
Simplify as needed.
