We know, circumference = 2πr
And radius = r
so, radius = 2πr/πr = 25.12/6.28 = 4 cm
So, OPTION A is your answer
Answer:
240000000 times bigger.
If we solve 3x10^8 we get 300000000
Then if we solve for 6x10^7 we get 60000000
Subtract those two using long subtraction to evaluate and we get 240000000
So, this is what it looks like
8+9x+4(11-2x)
You deal with the 4(11-2x) first.
44-8x
Combine like terms
44+8=52
9x-8x= x
One liter is 1,000 ml. plus 299 ml. is 1,299 ml. plus the additonal 398 ml. is 1,697 ml. which is 722 ml. less than the total volume. (722 ml. of water can still be added.)
Hello!
So, your equation for this problem would be—
x+4=3x
To solve this equation, you need to move the variables (x) to only one side of the equation.
So, you would use the Subtraction Property of Equality.
x+4=3x
-x -x
—————
4=2x
Now, your new equation is 4=2x.
Using the Commutative Property, we can reverse this to—
2x=4
Your next step is to find X. To do this, we can divide each side by 2.
2x=4
———
2 2
____
2/2=1. 4/2=2
Thus your new equation is—
X=2.
As a conclusion, there were 2 apples in the sack before you added the extra ones.
To check this, you could do
2+4= 6
6/3= 2
There were 2 apples originally in the sack.
Hope this helped!
