The equivalent expression of -(-5q-3.1r+4.5) without parenthesis is 5q + 3.1r - 4.5
In order to get the equivalent expression without parenthesis, we will use the distributive law. Also, we must know that:
- - × - =+
- + × - = -
- + × + =+
Given the expression -(-5q-3.1r+4.5)
This can also be written as -1 (-5q-3.1r+4.5)
On expansion
-1 (-5q-3.1r+4.5)
= -1(-5q) -1(-3.1t) -1(+4.5)
Using the sign rule, the result becomes:
= 5q + 3.1r - 4.5
Hence the equivalent expression without parenthesis is 5q + 3.1r - 4.5

Step-by-step explanation:
Answer:
1/18
Step-by-step explanation:
Assuming the die are regular 1,2,3,4,5,6
P(2) = number of 2's/ total numbers on die
= 1/6
Roll again
Assuming the die are regular 1,2,3,4,5,6
P (numbers greater than 4) = {5,6}/total numbers on die
=2/6 = 1/3
P (2, then number greater than 4) = 1/6 * 1/3 = 1/18
