Answer:

-21/8=j

Step-by-step explanation:

First Distrubute 9(j+2)

j-3=9j+18

Add 3 to both sides

j=9j+21

then subtract 9j

-8j=21

then divide by 8

j=-21/8

Answer:

40,320 ways

Step-by-step explanation:

From the above question, we know that there are 8 different coloured crayons

They are arranged in 2 rows, with 4 per row.

The number of different ways through which we can arrange the crayons is determined as:

Since each crayons are differently colored, any color can be first and any color can be in a different spot.

Therefore, this is calculated as:

8! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

= 40,320 ways.

Answer:

$\textsf{(a)} \quad (3x)^{\circ}+(x+14)^{\circ}=90^{\circ}$

$\textsf{(b)} \quad m \angle 1=\boxed{57}\:^{\circ}$

$m \angle 2=\boxed{33}\:^{\circ}$

Step-by-step explanation:

From inspection of the given diagram:

$m \angle 1=(3x)^{\circ}$

$m \angle 2=(x+14)^{\circ}$

A right angle is 90° and is represented by the ∟ symbol.

To find x, <u>equal</u> the sum of the angles to 90° and solve for x:

$\implies m \angle 1+m\angle2=90^{\circ}$

$\implies (3x)^{\circ}+(x+14)^{\circ}=90^{\circ}$

$\implies 3x+x+14=90$

$\implies 4x+14=90$

$\implies 4x+14-14=90-14$

$\implies 4x=76$

$\implies 4x \div 4=76 \div 4$

$\implies x=19$

To find the degree measure of each angle, substitute the found value of x into the expression for each angle.

$\implies m \angle 1=(3 \cdot 19)^{\circ}=57^{\circ}$

$\implies m \angle 2=(19+14)^{\circ}=33^{\circ}$

Answer:

<em>Probability ≈ 0.1071</em>

Step-by-step explanation:

Take combination and permutation into account;

$Total Number of Outcomes - 8C5,\\8 ! / 5! * ( 8 - 5 ) !,\\8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 / 5 * 4 * 3 * 2 * 1 * 3 * 2 * 1,\\\\Total Combinations = 56\\\\Number of Outcomes - 6C5,\\6 ! / 5! * ( 6 - 5 )! =\\\\Number of Outcomes = 6\\\\Conclusion; Probability = 5 / 56 = ( About ) 0.1071$
