1. The circumference if a circle can be found by multiplying pi (n = 3.14) by the diameter of the circle.

2. If a circle has a diameter of 4, it’s circumference is 3.14*4 = 12.56.

3. If you know the radius, the diameter is twice as large.

Answer:

(X, Y, Z) = (-2, 3, 3)

Step-by-step explanation:

We can subtract the second equation from the first to get ...

Y -Z = 0

We can add the third equation to the first to get ...

Z = 3

Then ...

Y -3 = 0 ⇒ Y = 3

and ...

X -3 -2(3) = -11

X = -2 . . . . . . . . . add 9

The solution is ...

(X, Y, Z) = (-2, 3, 3)

Add and simplify 1/5 + 1/10

aliya0001 [1]

In order to add these fractions we have to make a common denominator.

1/5 can turn into 2/10 Its the same thing. And its easier to solve with.

now lets multiply.

$\frac{2}{10}$ × $\frac{1}{10}$

Now we add across

2 + 1 = 3

------------

10 + 10 = 10 ( When adding fractions like these the denominator stays the same)

So your answer is...

$\frac{3}{10}$

Good Luck! :)
