There is not an answer to an expression.
-3+p is an expression, unless there was an equal sign and a sum at the end, that is when we can solve for the variable x.
-3+p simply equals -3+p
Answer:

Step-by-step explanation:
We need to note that this is an equation, in which we can solve for x.

We can use a calculator to find the tangent of 39 - we type 39 into the calculator then press the "TAN" button to find it's tangent. We find that to be around 0.81.
We now have the formula simplified down to
. To solve for x, we want to isolate it on one side, so we can multiply both sides by 68 to get rid of the fraction.
We know have 
, so x is approximately 55.
Hope this helped!
Answer:
The center is (2, -7)
Step-by-step explanation:
A circle is given by
(x-h)^2 + (y-k)^2 = r^2
where(h,k) is the center and r is the radius
(x - 2)^2 +(y + 7)^2 =169
(x - 2)^2 +(y - -7)^2 =13^2
The center is (2, -7) and the radius is 13
15 committees can be selected from a group of 6 people: 6×5×4×3/(4×3×2×1)=15. This the same as considering 2 people who aren’t selected: 6×5/(2×1)=15.
