Answer:
x=2
z=80
Step-by-step explanation:
Since (7x+66) and (11x+78) are a linear pair, their measures are supplementary and therefore add up to 180 degrees. z and (7x+66) are also vertical angles, meaning that they are equal.
7x+66+11x+78=180
18x+144=180
18x=36
x=2
z=7x+66=7(2)+66=14+66=80
Hope this helps!

Step-by-step explanation:
10*9*8*7*26
=131040
You can determine if the answer is positive or negative because the even numbers are positive and the odd numbers are negative
Answer:
For this case we have the following fraction:
To find the common denominator, what we must do is rewrite the fraction.
For this, we subtract fractions in the numerator and the sum of fractions in the denominator.
We have then:
We observe that the common denominator is given by the product:
Answer:
the common denominator is:
D)ab
Step-by-step explanation:
2 times x -4=12
2x-4=12
Let x= 8
(2.8)-4=12
16-4= 12
So the answer is 8
