Factoring has nothing to do with finding the least common denominator.

Answer:

probably FALSE

Step-by-step explanation:

The least common denominator (LCD) of two fractions is the least common multiple (LCM) of their denominators.

One of the ways to find the LCM of numbers is to factor them, then multiply the highest powers of each of the unique factors. Using this method makes your statement FALSE.

Another way to find the LCM is to multiply the numbers and divide that product by their greatest common denominator (GCD). Again, finding the GCD can involve factoring, as it is the product of all of the common factors of the numbers.

However, Euclid's algorithm is a method of finding the GCD that does not involve factoring. That is, it is entirely possible to find the LCM of two numbers without doing any factoring, per se. (Though, finding a divisor could be considered factoring.) Using this method makes your statement TRUE.

Our guess is that the desired answer is FALSE. Some methods of finding the LCD do involve factoring.

15 + (5-x)/x=30 solve for x

elixir [45]

Answer:

5/16

Step-by-step explanation:

15+(5-x)/x=30

1) Subtract 15 from both sides:

(5-x)/x=15

2) Multiply both sides by x:

5-x=15x

3) Add x to both sides:

16x=5

4) Divide both sides by 16:

x=5/16

Help me please I been trying to figure out how to do this problem

sin 30 = x/4

sin 30 = 0.5

0.5 = x/4

x = 2

Plug the points into the equation.
Ex. y=3x-5
(X,y)
1. (5,10): 10=3(5)-5
15-5=10; point 1 is valid
-1=3(-2)-5
-1=-6-5
-1 does not equal -11
Point 2 is not valid
Same process for letter B

A phone company charges $0.06 per minute for local calls and $0.15 per minute for international calls. When your bill comes, it

solmaris [256]

Let's assume two variables x and y which represent the local and international calls respectively.

x + y = 852 = total number of minutes which were consumed by the company (equation 1)
0.06*x+ 0.15 y =69.84 = total price which was charged for the phone calls (Equation 2)
from equation 1:-
x=852 -y (sub in equation 2)
0.06 (852 - y) + 0.15 y =69.84

51.12 -0.06 y +0.15 y =69.84 (subtracting both sides by 51.12)
0.09 y =18.74
y= 208 minutes = international minutes (sub in 1)
208+x=852 (By subtracting both sides by 208)
x = 852-208 = 644 minutes = local minutes
