Does x-4=5 has one solution

Answers

Answer 1

Answer: Yes, if you do it correctly by following the Algebraic way you would get:

x-4=5
you need to find x.
you can do this by subtracting 4 from the x side and adding it to 5.
so it would be x= 5+4
then you jsut add 5 and 4 and you get x.
so x = 9.

Answer 2

Answer: Hi there! If you add 4 to both sides, x-4+4=5+4 which gets us 9. Therefore, x-4=5 does have a solution. The solution is 9.

Find the unit rate for number of parts manufactured per hour if 1116 parts are made in 7 hours. Round to the nearest integer.A. 209 parts/h

B. 127 parts/h

C. 159 parts/h

D. 183 parts/h

Answers

The unit rate is obtained by dividing the amount of work done by the unit time. In the problem, we are already given the total number of parts manufactured (amount of work done) and the total amount of time to manufacture (7 hours).

Obtaining the unit rate is as simple as dividing 1116 parts by 7 hours, as shown below:

Unit rate = 1116 parts / 7 hours
Unit rate = 159.42857

Therefore the unit rate is approximately 159 parts/h.
