Answer:
x = 13
Step-by-step explanation:
Note that the side length x is opposite of the right angle, which means that it is the hypotenuse, which will usually be denoted as c.
Set the equation:
a² + b² = c²
let:
a = 5
b = 12
c = x
Plug in the corresponding numbers (& x) to the corresponding variables:
(5)² + (12)² = (x)²
Simplify. First, solve for the power, and then add:
x² = (5²) + (12²)
x² = (5 * 5) + (12 * 12)
x² = 25 + 144
x² = 169
Next, root both sides of the equation:
√x² = √169
x = √169 = √(13 * 13) = 13
x = 13
~
Note the rules, and it should be easier:
30-60-90° = 1 , √3 , 2
45-45-90° = 1 , 1 , √2
Any other measurements use the equation: a² + b² = c²

Solve the system ... y=3x-8 and y=-9x+4
Answers
[2] y + 9x = 4
-3x + y = -8 9x + y = 4
Solve equation [2] for the variable y
[2] y = -9x + 4
// Plug this in for variable y in equation [1]
[1] (-9x+4) - 3x = -8
[1] - 12x = -12
// Solve equation [1] for the variable x
[1] 12x = 12
[1] x = 1
// By now we know this much :
y = -9x+4
x = 1
// Use the x value to solve for y
y = -9(1)+4 = -5
{y,x} = {-5,1}
Mr Lee has a family of 6 people and Mrs Scarlett has a family of 4. They were given 15 kg of chocolate
when they visited a chocolate factory for work. If they decide to share it so that each family
member gets an equal amount, determine the required ratio and hence calculate how much
chocolate Mr Lee and Mrs Scarlett will each take home to their families.
Answers
Answer:
Mr. Lee takes home 9 kg of chocolate.
Mrs. Scarlet takes home 6kg of chocolate.
Step-by-step explanation:
Mr. Lee has a family of 6 people, and Mrs. Scarlett has a family of 4 people.
Together, the total number of people is 6 + 4 = 10
If we divide evenly the chocolate between all 10, then each one gets the same amount.
Then we need to do the quotient:
15kg/10 = 1.5kg
This means that each person gets 1.5kg of chocolate.
And Mr. Lee has 6 on his family, then the amount of chocolate that Mr. Lee takes home is 6 times 1.5 kg
6*1.5kg = 9kg
Mr. Lee takes home 9 kg of chocolate.
Mrs. Scarlett has a family of 4 people, then she takes home 4 times 1.5kg of chocolate, this is:
4*1.5kg = 6kg
Mrs. Scarlet takes home 6kg of chocolate.

|2n|-4=8 solve for n
Answers
Answer:
n = ± 6
Step-by-step explanation:
absolute value equations usually produce 2 solutions
to get the positive solution just solve normally: 2n - 4 = 8
2n = 12
n = 6
to get the negative solution you must take what is in the absolute value bars and multiply by negative one: -(2n) - 4 = 8
-2n - 4 = 8
-2n = 12
n = -6

MULTIPLE CHOICE 9th grade math: help me find the formula to the nth term:
Answers
Answer:
[tex]a_{n}[/tex] = - 5n - 2
Step-by-step explanation:
There is a common difference between consecutive terms, that is
- 12 - (- 7) = - 17 - (- 12) = - 5
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 7 and d = - 5, then
[tex]a_{n}[/tex] = - 7 - 5(n - 1) = - 7 - 5n + 5 = - 5n - 2

8° + 6x is an exterior angle. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.
In this situation, those two angles are 30° and 4x+2°
So lets put this in an equation
30° + 4x + 2° = 8° + 6x
4x + 32° = 6x + °8
Now lets subtract 8° from both sides to make it simpler
New equation =
4x + 24° = 6x
Lets evaluate X=
6x - 4x = 24°
2x = 24°
x= 24/2
x= 12°
