Answer:
The answer is d = C/pi.
Step-by-step explanation:
To solve this equation for the variable d, we must isolate it on the right side of the equation. It is currently being multiplied by pi, so to reverse this action, we should divide both sides of the equation by pi.
c = (pi) * d
c/pi = pi/pi * d
c/pi = d
d = c/pi
Therefore, the answer is d = C/pi.
Hope this helps!
Answer:
4
Step-by-step explanation:
4x+5+3x-2=31
7x+3=31
7x=28
x=4
Answer:
x> 30
Step-by-step explanation:
+ First, is the inequation 3x - 52 > 28.
+ If Yes, so we can solve:
3x - 52 > 28
3x - 52 + 52 > 28 +52
3x > 90
3x/3 > 90/3 (divide both sides by 3>0)
x > 30
Answer:

or

Step-by-step explanation:
-7,-3,1,5,... is a arithmetic sequence.
Arithmetic sequences have a common difference. That is, it is going up by 4 each time.
When you see arithmetic sequence, you should think linear equation.
The point-slope form of a line is
.
m is the common difference, the slope.
Any they are using the point at x=1 in the point slope form. So they are using (1,-7).
So let's put this into our point-slope form:


Subtract 7 on both sides:

So your answer is
