DF=9x-39
DE=47
EF=3x+10
47+3x+10=9x-39
47+10+39=9x-3x
96=6x
16=x

Combine DE and EF together for 47 + 3x + 10 for 57 + 3x
Then combine like terms from both sides, so 57 + 3x = 9x - 39
After your adding and subtracting you should get 96 = 6x
After dividing both sides by 6 to get x by itself, you get 16 = x
Plug 8 in for x into 3(16) + 10 for a final answer of 58.
You can check doing 47+58 = 105 by making sure both sides equal.

x=4.2.

Answer:

See below.

Step-by-step explanation:

In symbols, the Law of Detachment is:

If p, then q. (This is a true statement.)

p is true.

Conclusion: q is true.

Explanation of the Law of Detachment with words and an example.

A conditional is given and is true. Then the hypothesis is given as true. By the Law of Detachment, you can conclude the conclusion of the conditional is true.

Example:

Conditional: If it rains, the grass is wet. (This is a conditional given as a true statement.)

Statement: It is raining. (This is the hypothesis of the conditional given as a true statement.)

Conclusion by the Law of Detachment: The grass is wet. (We conclude that the conclusion of the conditional is true.)

Now your problem:

Conditional: If Jillian gets a raise, then she will buy a new car.

Statement: Jillian got a raise.

Conclusion by the Law of Detachment: Jill will buy a new car.
