Answer:
The option with “at most” and “no more than”
Step-by-step explanation:
These two phrases mean “greater than or equal to”
1. The sum of 1.5 and the product of 6.5 and a number is no greater than 21.
2. The product of 6.5 and a number, when increased by 1.5, is at most 21.
In which mathematical expression both sides are not equal, i.e. one side is greater or less or greater equal or less equal than other side, is called inequality.
Example : 4x+5>3x-2
The given inequality is [tex]6.5x+1.5\leq 21[/tex]
Firstly, The sum of 1.5 and the product of 6.5 and a number (say x) is 6.5x+1.5, which is no greater than 21, i.e. [tex]6.5x+1.5\leq 21[/tex]
Again, The product of 6.5 and a number (say x) is 6.5x, when increased by 1.5, it will be 6.5x+1.5 which is at most 21, i.e. [tex]6.5x+1.5\leq 21[/tex]
Hence, the correct options are,
1. The sum of 1.5 and the product of 6.5 and a number is no greater than 21.
2. The product of 6.5 and a number, when increased by 1.5, is at most 21.
