Answer:
5%
Step-by-step explanation:
2000/40000 = 0.05
All you do is divide both numbers and you'll get the decimal form which in this case is 0.05 which means 5%.
For this case we have that by definition, the circumference of a circle is given by:

Where:
d: It is the diameter of the circle
They tell us that:

Substituting:

Thus, the circumference of the circle is 55 centimeters.
Answer:
Option B
Second one is correct, that is an identity.
Third one is a contradiction:
6x - 15 = 3 * (2x - 6) ------> 6x - 15 = 6x - 18
Fourth one:
5x - 3 * (x - 4) = 2 * (x - 6) ---> 5x - 3x + 12 = 2x - 12 ---> 2x + 12 = 2x -12
So this is a contradiction as well.
Answer: Let's solve for x.
2x−10y=10
Step 1: Add 10y to both sides.
2x−10y+10y=10+10y
2x=10y+10
Step 2: Divide both sides by 2.
2x
2
=
10y+10
2 answer
x=5y+5
Step-by-step explanation:
Let's solve for s.
sx+9y=9
Step 1: Add -9y to both sides.
sx+9y+−9y=9+−9y
sx=−9y+9
Step 2: Divide both sides by x.
sx
x
=
−9y+9
x
s=
−9y+9
x
Answer: hope this helps:)
s= -9y+9/x
