Answer:
42 1/7 degrees
Step-by-step explanation:
65+7x=360
7x=295
x=42 1/7
Is means =
less than is subtract
1/2a -8=2

Answer:

Step-by-step explanation:
The given equation is :

We need to find the value of x.
When the exponent 2 removes from LHS, it will shift to RHS as square root as follows :

We know that, 4×4= 16 and 5×5 = 25
So,

So, the solution of the given equation is 4/5.
The formula is x1+x2 divided by 2 and y1+y2 divided by 2.I hope this is what you where looking for
In this question , we have to simplify the given ratio, which is
12xy:3x
First we have to see which factor is common in numerator and denominator,
We can write 12 as 3 times 4, that is

So the common factor is 3x.
In the next step, we cancel out 3x

And that's the required simplified form .
