Answer:

<h2>x = 11</h2><h2 />

Step-by-step explanation:

The equation represents as:

285 − 5x = 340 − 10x

combine similar terms:

285 - 340 = 5x - 10x

simplify:

-55 = -5x

divide -5 on both sides:

x = 11

285-5x=340-10x

285-5x-(340-10x)=0

-5x-(-10x+340)+285=0

-5x+10x-340+285=0

5x-55=0

5x=55

x=55/5

x=11

Answer:

n(A) = 5 + 7 =12

n(B) = 7 + 3 = 10

n(A n B) = 7

n(A u B) = n(A) + n(B) - n(A n B)

5 + 3 - 7 = 1

n(A')=3

n(B')=5

Answer:

Therefore,

C=\pi d\\C\approx 3.14 \times d\\C\approx 43.96\ inches

Step-by-step explanation:

Let Assume Some Diameter of a Circle, to Solve it

Diameter = d = 14 inch ( say )

C =Circumference

Pi =constant = 3.14

To Find:

C = ?

Solution:

Formula for Circumference of a Circle is given as

C=\pi d

Where,

C = Circumference

d = Diameter

Now Substitute d = 14 inches we get

C=3.14\times 14\approx 43.96\ inches

This way we can find the circumference for any 'd' i.e Diameter

Therefore,

C\approx 43.96\ inches

When solving the equation, which is the best first step to begin to simplify the equation?
boyakko [2]

Answer:

<h3>Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)</h3>

Step-by-step explanation:

Given the expression

- 2 (x + 3) = - 10

The first step in solving the expression is to multiply both sides by -1/2 as shown;

-1/2(-2)(x+3) = -1/2(-10)

(x +3) = 1/2(10)

x + 3 = 5

x = 5-3

x = 2

Hence the correct option is Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)
