Answer:
Step-by-step explanation:
Length of:
First piece = x
Second piece = 4x
Third piece = 5x
Equation: 30 = 4x + 5x + x
Solving the Equation:
10x = 30
x = 3
Lengths of:
First piece = 3 inches
Second piece = 12 inches
Third piece = 15 inches
a) substitution (refer to statements 1 and 2)
b) definition of supplementary
c) subtraction property of equality
Answer:
Step-by-step explanation:
Given:
using the properties of log we can take the power 1/2 and multiply it.
now we can differentiate:
this is our answer!
The answer would be either:
-99/10 or -9 9/10
Factories both equations:
5(x - 4) / (x + 2)(x - 4)
Then take out the common brackets:
5 / x + 2
Minus 2 from both sides:
3 / x
If you are looking for the greatest common factor of the numerator and denominator, the answer would be (x - 4)
