Answer:
192 + 4( 7a + 6 )
DISTRIBUTE
192 + 28a + 24
ADD THE NUMBERS
216 + 28a or 28a + 216
Step-by-step explanation:
U DON'T HAVE TO TYPE "DISTRIBUTE" and "ADD THE NUMBERS"
If i simplify number 6 it would be -55/63
Check the table attached.
The first coordinates of each pair represent the 1.roll, and the second coordinates the 2nd, roll.
All the possible outcomes are {(1, 1), (1, 2).... (6, 5), (6, 6)}, a total of 36, as can be seen in the table.
Each outcome has a chance of 1 out 36 total possible outcomes of occurring.
So the probability is 1/36=0.02778
Part(A):
To solve the system of Linear equations using Substitution:

Consider the first equation, x+y=7 implies x=7-y













PArt(B): Use a graph to verify your answer to the system:
Using Desmos graphing calculator, graph the two equations.
