The answer for the question is D
Answer: The value of x in a vertical angle is 25.
Step-by-step explanation:
So far the givens are:
a vertical angle with 5x + 4 degrees and 8x - 71 degrees
We know that all vertical angles are congruent. Therefore, we also know that the two given equations are equal. So knowing that, we can do:
5x + 4 = 8x - 71
Group like terms:
71 + 4 = 8x - 5x
75 = 3x
25 = x
Hence your answer.
1 yard = 36 inches
8 yards = 288 inches
He has 288 inches of ribbon.
We are given this:
First step is to get rid of brackets. There is no sign in front of first brackets, so we do not change the sign. In front of second brackets there is negative sign so we need to change sign for each term inside of those brackets.
Next step is to group terms with same exponent in descending order.
Now we add or substract terms with same exponent.
Standard form means ordering terms in a descending order of an exponent.
