4x+11+7x-6+43= 180
11x = 132
x = 12
7(12)-6 = 78
RTS = 78 degrees
Answer:
b
Step-by-step explanation:
a: is not because in the distribution property, the answer would be for a, 9x+63.
b: yes.
c: it's subtracting, not adding. The question states adding
d: 7 is not the one being multiplied in the question, 9 is. Therefore b is right
The explaining is not good but im pretty sure it's b..
Let
and
be these consecutive integers. For some base
, we can write


If

then

Now,



Squaring both sides gives

and so



(because the base has to be non-zero)
Answer:
In this equation n = 15
Step-by-step explanation:
In order to find this, we first must make each term a base 3. Since 9 is 3 squared, we can change it easily to base 3.
3^5 * 9^5 = 3^n
3^5 * (3^2)^5 = 3^n
3^5 * 3^10 = 3^n
3^15 = 3^n
Now that we have both in simple term of 3 raised to a power, we can eliminate the 3's and see that 15 = n
Answer: There were 32 teachers.
Step-by-step explanation:
(215 - 23)/6 = amount of teachers
215 - 23 = 192
192/6 = 32
