Mathematics

Answer:

Both equations have no solution.

Step-by-step explanation:

The first equation is:

x + 2 = x + 4

Group the similar terms to get:

x  - x =  4 - 2

0 =  - 2

This equation has no solution because

0 \ne - 2

The second equation is

5(w - 1) - 2 = 5w + 7

We expand the parenthesis to obtain:

5w - 5 - 2 = 5w + 7

5w - 7= 5w + 7

Group similar terms:

5w -5w = 7 + 7

0 = 14

This equation does not also have solution because

0 \ne14

Answer:

Percent error is approx. 22%

Step-by-step explanation:

So to do this you need to know the formula for percent error, which is

percent error = l measured - theoretical / theoretical l * 100%

With this just plug in 18 (real) and 14 (measured).

percent error = l 14 - 18 / 18 l * 100%

percent error = l -4 / 18 l *100%

percent error = l -2/9 l *100%

You then do absolute value because the percent error must be positive not negative! So -2/9 becomes 2/9. You then divide 2/9 to get approx. 0.22... and you muliply by 100% to get 22%.
