For what values of p is the value of the binomial 1.5p−1 smaller than the value of the binomial 1+1.1p by 4?
77julia77 [94]

Answer:

  p = -5  (only)

Step-by-step explanation:

It looks like we want to count solutions for ...

  (1.5p -1) = (1 +1.1p) -4

  0.4p = -2

  p = -2/0.4 = -5

For p having a value of -5, the binomial (1.5p -1) = -8.5 will be smaller than the value of (1 +1.1p) = -4.5 by 4.

The sum of 86, 68, and 38 is 192. What else do you know about the sum of 68, 38, and 86?
Sveta_85 [38]
<span>We have 2 given numbers:
=> 86 + 68 + 38 = 192
=> 68 + 38 + 86 = 192 also
This kind of process used commutative property system of equation in where:
a + b = b + a
No matter what sequence you are going to use, the answer would always be the same.
In the given 2 equations, notice that both digits of 2 group of equation contains the same number. The only difference is they were added with different orders. Yet the answers are still the same.
