Answer:
Find the LCD of the first two, then the LCD of that and the third one.
Step-by-step explanation:
You can do it by finding the LCD of two of the denominators, then the LCD of that and the third denominator.
Or, you can factor each of the denominators and find their LCM by multiplying the unique factors to their highest powers.
___
<u>Example:</u>
1/21 + 1/35 + 1/45
The LCD of 1/21 and 1/35 is (21·35)/5 = 105. The LCD of 1/105 and 1/45 is ...
(105·45)/15 = 315
__
Using factoring ...
- 21 = 3·7
- 35 = 5·7
- 45 = 3²·5
LCD = 3²·5·7 = 315
Answer:
By definition, Proportional relationships have the following form:
y=kxy=kx
Where "k" is the Constant of proportionality.
By definition the graph of a proportional relationship is a straight line that passes through the origin (Point (0,0)(0,0) ).
Knowing this and having the relationship provided in the exercise, you can identify from the table that when:
x=0x=0 , y=32y=32
Then, the line does not pass through the origin, so you can conclude that the relationship between the temperature scales is not proportional.

Step-by-step explanation:
What you do is you multiply 2 ten times
2x2x2x2x2x2x2x2x2x2=1024
Answer:
Keep the exponential expression by itself on one side of the equation.
Get the logarithms of both sides of the equation. You can use any bases for logs.
Solve for the variable. Keep the answer exact or give decimal approximations.

Answer:
y = 32.5
x = 13
Step-by-step explanation:
opposite angles of the parallelogram are equal to each other.
parallelograms form 360° in total
so 60+ 55 = 115 * 2 (because two angles) = 230
360 - 230 = 130 (divide this by two to get one angle of the parallelogram) so 65°
2y = 65 °. and 5x = 65 °
y = 32.5
x = 13
