Answer:
Step-by-step explanation:
the circumference of the circle, C=2*3.14*r
C=3.14*d
C=3.14*12=37.68
You need to expand the brackets before you can simplify, so:
-3 × 10x = -30x
-3 × 4y = -12y
6 × 6x = 36x
6 × -2y = -12y
So now you have (-30x - 12y) + (36x - 12y)
-30x + 36x = 6x
-12y + -12y = -24y
So your answer is 6x - 24y. I hope this helps!
Answer:
She has 100 ounces.
Step-by-step explanation:
Since one bag has 8 apples, two of the bags have 8 apples and the one half bag of apples has 4 apples.
Then, since each apple weighs 5 ounces you multiply:
Equation:
= 2 1/2 × 8
= 5/2 × 8
= 40/2
= 20
20 x 5 = 100
Answer:
Circumference of a circle= 
Step-by-step explanation:
The circumference of any circle is the total length of its boundary which can be calculated by the formula:
Circumference of a circle=
Where 'r' is the radius of the circle
For, the given circle the circumference can be find in terms of 
by putting some value of radius in the formula, which gives the circumference in terms of .
