valkas [14]

3 ( 3x + 6 + x ) = 1

Step 1, apply distributive method.

9x + 18 + 3x = 1

Step 2, simplify the following

12x + 18 = 1

Step 3, Change side

12x = -17

Final answer

x = -17/12

The error/mistake was in step 2 where [ 9x +3x = 12x ]

Recheck the answer

3 ( 3x + 6 + x ) = 1

3 ( 3(-17/12) + 6 + -17/12 ) = 1

1 = 1

Hence proved our solution is correct.

Answer:

1/20 or 0.05

Step-by-step explanation:

The probability of getting yellow:

1/5

The probability of getting a lion rubber band:

1/4

The probability of getting two events (getting yellow, getting a lion) are independent, so we have to multiply the two probabilities to get:

(1/5) × (1/4)
1/20 or 0.05

Fynjy0 [20]

Answer:

(a)

$\begin{array}{ccc}{} & {W} & {w} & {w} & {Ww } & {ww } & {w} & { Ww} & {ww } \ \end{array}$

(b)

$White = 50\%$

$Yellow = 50\%$

Step-by-step explanation:

See attachment for initial punnet square

Solving (a): Complete the square

Initially, we have:

$\begin{array}{ccc}{} & {W} & {w} & {w} & { } & { } & {w} & { } & { } \ \end{array}$

To complete the square, we simply write the letter at the column and the letter at the row in each cell;

So, we have:

$\begin{array}{ccc}{} & {W} & {w} & {w} & {Ww } & {ww } & {w} & { Ww} & {ww } \ \end{array}$

Solving (b): Percentage of each

From the question, we understand that W are dominant to w.

So:

$Ww = White$

$ww = Yellow$

From (a) above

$Ww = 2$

$ww = 2$

$Total = 4$

So, the percentage of each is:

$White = \frac{Ww}{Total} * 100\%$

$White = \frac{2}{4} * 100\%$

$White = 0.5 * 100\%$

$White = 50\%$

$Yellow = 100\% - White$ --- Complement rule

$Yellow = 100\% - 50\%$

$Yellow = 50\%$
