Answer: Original expression: 2x - 11 + 4x + 7 + 3(x-4)
Simplified: 9x - 16
Step-by-step explanation:
2x - 11 + 4x + 7 + 3(x-4) becomes 2x - 11 + 4x + 7 + 3x -12
Group like terms, then combine to simplify:
2x + 4x + 3x -11 + 7 - 12
2x + 4x + 3x = 9x
-11 -12 + 7 = =23+7= -16
Simplified expression: 9x - 16
2(8x + 2) - 5 + 5x
2(8x) + 2(2) - 5 + 5x
16x + 4 - 5 + 5x
16x - 1 + 5x
16x + 5x - 1
21x - 1
Answer:
AAAAAAA!!!!!
Step-by-step explanation:
Answer:
It can not be simplified after 3/10 so it stays that way
Step-by-step explanation:
1/2=5/10
1/5=2/10
5/10-2/10=3/10

Step-by-step explanation:
This is a matrices. Since they are both the same in format, we can add them together. But first we must multiply each value by the given values.
