Answer: 5 and 3
Step-by-step explanation:
Answer:
30 hrs
Step-by-step explanation:
In 1 hour, J completes 1/55 of job
In that time, D completes 1/66 of job
J + D together complete 1/55 + 1/66 of the job in 1 hour
1/55 + 1/66 = 1/30
Together, it takes them 30 hours to build the wall.
The general formula for a perimeter of rectangle is 2x(length+width). Here 20 is length and 8 is width. 2x(20+8). 2x(28). 56. The answer is 56.
Option C
3x + 7 > 4x is the inequality for sum of three times a number and seven is greater than four times the number
<em><u>Solution:</u></em>
Given that the statement is:
The sum of three times a number and seven is greater than four times the number
We have to find the inequality that represents the above statement
Let the number be "x"
Therefore,
sum of three times "x" and seven is greater than four times "x"
Here "times" represents product or multiplication
Thus we get,
three times "x" + 7 > 4 times "x"

Thus the inequality is found. Option C is correct
