Answer with explanation:
Total amount of money , that Michael can spend on office supplies = $ 234
Cost of one ream of paper= $ 6
Cost of one ink cartridge = $ 18
let number of ream of paper bought = x
And, number of ink cartridge bought = y
Now, the above statements about the problem , which can be written in the form of inequality
6 x + 18 y ≤ 234
6× (x+ 3 y)≤ 6 × 39
→→x + 3 y ≤ 39
Drawing the graph of inequality
x and y will take only positive integral value.
Answer:
He pays to the cab driver for 25 miles.
Step-by-step explanation:
Consider the provided information.
Let us consider he walks x miles at the rate of 4 miles per hour.
As we know
Therefore, time taken is:
He get a taxi for (31-x) miles at the rate of 50 miles per hour.
Therefore, time taken is:
It took 2 hours after he started.
That means the sum of time take is 2 hours.
Hence he walk 6 miles and he get a taxi for 31-6=25 miles.
He pays to the cab driver for 25 miles.
For this case we must pose a verbal problem equivalent to the following expression:
So, we have:
The sum of double a number plus five.
We propose the expression:
A number subtracted from the sum of double the same number plus five equals twenty-six.
Answer:
A number subtracted from the sum of double the same number plus five equals twenty-six.
