The difference between two numbers is 25. The smaller number is 1/6th of the larger number. What is the value of the smaller number?

Answers

From the given word problem, the smaller number is 5

The difference between two numbers is 25. The smaller number is 1/6th of the larger number. What is the value of the smaller number?

Let's assume the smaller number is represented by x and the larger number is represented by y.

According to the given information in the word problem, the difference between the two numbers is 25. This can be expressed as:

y - x = 25 (Equation 1)

It is also stated that the smaller number is 1/6th of the larger number:

x = (1/6) * y (Equation 2)

To find the value of the smaller number (x), we can substitute Equation 2 into Equation 1:

y - (1/6) * y = 25

Multiplying through by 6 to eliminate the fraction:

6y - y = 150

5y = 150

Dividing both sides by 5:

y = 30

Substituting the value of y back into Equation 2:

x = (1/6) * 30 = 5

Therefore, the value of the smaller number is 5.

Find three consecutive numbers whose sum is 138 by writing and solving an equation

Answers

Your 3 variables in this equation would be:
x
x+1
x+2
as you need these numbers to be consecutive. Because it is asking for the sum, you need to add these three variables and set them equal to 138:
(x)+(x+1)+(x+2)=138
At this point the parentheses don't matter, so they can be removed:
x+x+1+x+2=138
Combine like terms:
3x+3=138
Subtract the three:
3x=135
Divide 135 by 3:
x=45
Then, plug 45 back into the other two variable equations:
45+1=46
45+2= 47
Your 3 consecutive integers are 45, 46, and 47

$x+x+1+x+2=138\n3x+3=138\n3x=135\nx=45\nx+1=46\nx+2=47$

Those numbers are 45,46,47.

Let f(x)=√4x and g(x)=x+6, whats the smallest number that is the domain of f^o g?

Answers

f(x) = √(4x)
g(x) = x + 6

(f ο g)(x) = f(g(x))
(f ο g)(x) = √(4(x + 6))
(f ο g)(x) = 2√(x + 6)

The smallest number that is the domain of (f ο g)(x) is -6.
