First step: multiply the 5(x3) and it will give you x15 or most commonly written as 15x. you should now have 15x-(-20).
Second step: since you cannot subtract -20 from 15x because it has a variable, the final answer is just 15x-(-20), or 15x+20.
Step-by-step explanation:
7+2x-2 = 4x -3
5= 2x -3
2x = 8
x = 4
Answer:
D. pi
Step-by-step explanation:
Circumference of a circle = 
Diameter = d
Therefore, ratio of circumference of a circle to its diameter would be:

=> (d cancels d)
Therefore, the ratio of the circumference of a circle to its diameter is
