I got 5. If you divide 210 by 3, you get 40 miles an hour. You then divide 200(miles) by 40(how fast your going) to get 5.

Example 2: x=10

Example 3: x=-1

Example 4: x=35

Example 5: a-b+c=9

Example 6: x=1, x=1/2

Further explanation:

<u>Example 2:</u>

\sqrt{4x-4} =6

Taking Square on both sides

(\sqrt{4x-4})^2 =(6)^2\\4x-4=36\\4x=36+4\\4x=40\\\frac{4x}{4}=\frac{40}{4}\\x=10

<u>Example 3:</u>

9+\sqrt{4x+8}=11

Subtracting 9 from both sides

9-9+\sqrt{4x+8}=11-9\\\sqrt{4x+8}=2\\

Taking Square on both sides

(\sqrt{4x+8})^2=(2)^2\\4x+8=4\\4x=4-8\\4x=-4\\\frac{4x}{4}=-\frac{4}{4}\\x=-1

<u>Example 4:</u>

8+\sqrt{x+1}=2

subtracting 8 from both sides

8-8+\sqrt{x+1}=2-8\\\sqrt{x+1}=-6

Taking Square on both sides

(\sqrt{x+1})^2=(-6)^2\\x+1=36\\

Subtracting 1 from both sides

x+1-1=36-1\\x=35

<u>Example 5:</u>

\sqrt{a-b+c}=3

Taking Square on both sides

(\sqrt{a-b+c})^2=(3)^2\\a-b+c=9\\

<u>Example 6:</u>

2\sqrt{2x-1}=4x-2

Taking square on both sides

(2\sqrt{2x-1})^2=(4x-2)^2\\4(2x-1)=16x^2+4-16x\\8x-4=16x^2-16x+4\\8x=16x^2-16x+4+4\\8x=16x^2-16x+8\\16x^2-16x-8x+8=0\\16x^2-24x+8=0

dividng whole equation by 8

2x^2-3x+1=0\\2x^2-2x-x+1=\\2x(x-1)-1(x-1)=0\\(2x-1)(x-1)=0\\2x-1=0 => x=\frac{1}{2}\\x-1=0 => x=1

Answer:

−5+11i

Step-by-step explanation:

(3+6i)−(8−5i)

Subtract 8−5i from 3+6i by subtracting the corresponding real and imaginary parts.

3−8+(6−(−5))i

Subtract 8 from 3. Subtract −5 from 6.

sasho [114]
A. The theoretical probability for pink is 95/185 or about 51.35%

B. The theoretical probability for brown is 90/185 or about 47.82%.

C. To find the experimental probability, we will make another fraction. The number of outcomes will be the numerator and the total will be the denominator.

Pink  36/69 = 52.17%
Brown  33/69 = 47.82%
