Given:
I'm 3 times younger than my mom but 3 times older than my younger brother.
Mom is older than my younger brother by 40 years.
To find:
How old am I.
Solution:
Let x be the age of the younger brother.
I'm 3 times older than my younger brother. So, my age is 3x.
I'm 3 times younger than my mom. So, she is 3 times older than me and her are is 3(3x)=9x.
The difference between the age mother and younger brother is 40 years.
[tex]9x-x=40[/tex]
[tex]8x=40[/tex]
Divide both sides by 8.
[tex]x=\dfrac{40}{8}[/tex]
[tex]x=5[/tex]
Now,
My age [tex]=3x[/tex]
[tex]=3(5)[/tex]
[tex]=15[/tex]
Therefore, I'm 15 years old.

Solve for b:
2b = 36
Answer:
b = 18
Step-by-step explanation:
1st step is isolating b by moving 2 to the other side. When you move a number the the other side it flips (from + to - or × to ÷). The 2 in this question is being multiplied my b (no sign means multiply) so when you move it to the other side it becomes 36/2 or 18
Steps:
2b=36
b=36/2
b=18
Answer:
b=18
Step-by-step explanation:
2b=36
Divide both sides by 2
b=36/2
then divide 36 by 2 to get 18

find the value of x to make L||m
6x+8
4x+2
Answer:
the value of x is -3
Step-by-step explanation:
The computation of the value of x is shown below:
Given that
6x + 8
4x + 2
Now equate these two equations
6x + 8 = 4x + 2
6x - 4x = 2 - 8
2x = -6
x = -3
Hence, the value of x is -3

If the total length of all the meteors were distributed equally between each meteor, how long would each one be?
one and one thirty sixth inches
one and one thirty eighth inches
one and one fortieth inches
one and one forty second inches
Answer:
I am guessing 1 4/40
Step-by-step explanation:
hope this works!
If the total length of all the meteors were distributed equally between each meteor, one and one fortieth inches long would be each meteors. Therefore, the correct option is option C.
What is length?Distance is measured in length. Length has the dimension of distance in the International Order of Quantities. The majority of measurement systems choose a particular design for length from which all further units are derived. The metre serves as the foundational unit of length in the International Order of Units (SI) system.
Most people understand length to refer to an object's longest dimension. However, depending on the object's position, this may or may not be the case. If the total length of all the meteors were distributed equally between each meteor, one and one fortieth inches long would be each meteors.
Therefore, the correct option is option C.

What is a hyperbola?The hyperbola is the locus of a point such that the difference of distance from point P to two non-movable points. These two points are called foci of hyperbola.
An asymptote is a line that constantly reaches a given curve but does not touch at an infinite distance.
The function is given below.
f(x) = [5 - 5x²] / x²
The equation of the vertical asymptote will be at x = 0. And the equation of the horizontal asymptote is given as,
f(x) = [5 - 5x²] / x²
f(x) = [5(1 - x²)] / x²
f(x) / 5 = [1 - x²] / x²
The equation of the horizontal asymptote will be y = - 5.

Michael is saving to buy his senior ring. The base cost of the ring is $280 plus any upgrades he wants to purchase. If he saves $35 each month, which solution represents how many months, x, it will take Michael before he can purchase his ring?
Answer:
8
Step-by-step explanation:
280/35=x
This is only for the base cost.
You can also right this as:
35(X)=280 and solve for x
35(X)=280
/35 /35
x=8
Hope this helps, good luck!
The solution that represents how many months, x, it will take Michael before he can purchase his ring is "x ≥ 8". The correct answer would be option (B)
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
It will take Michael 8 months or more to save enough money to buy his senior ring. We know this because the inequality "x ≥ 8" means "x is greater than or equal to 8".
In other words, x can be equal to 8 or any number greater than 8.
So if Michael saves $35 each month, it will take him at least 8 months to save $280.
Hence, the solution is "x ≥ 8".
