Step-by-step explanation:
Rs 720
Cost of 1 m of cloth = 450/5= Rs 90
Cost of 8 m of cloth= 90*80= Rs 720
23
because
the pattern is
(5 10) ..1.. (15 20) ..2.. (25 30) ..3..
..1... = 3
..2.. = 13
so ..3.. = 23
Answer:
In order to change a rational number to a decimal, we just convert the number into the form of a fraction. We then divide the numerator with the denominator and find out the exact value of the division.
We are given the following inequality:

If we replace b = 2, we get:

Now we solve for "a" first by subtracting 8 on both sides:

Now we divide both sides by 6

Simplifying:

Therefore, for b = 2, the possible values of "a" are those that are greater than 1/3
