It is: 3x-11
we have to remove the unnecessary parentheses then we have to expand: x-4+2x-7
Finally we collect the like terms and calculate
that’s why the answer is 3x-11

Answer:

3x - 11

Step-by-step explanation:

( x - 4 ) + ( 2x − 7 )

*it's better to take away the parenthesis

x - 4 + 2x - 7

Combine like terms

( x with 2x, and -4 with -7)

3x - 11

And you cannot simplify it anymore

Hope this helped!

4/9+(x-1)=28/9-(x-7x)+1
k0ka [10]

4/9 + (x-1) = 28/9 - (x-7x) + 1

4/9 + x - 1 = 28/9 - x + 7x + 1

-5/9 + x = 37/9 + 6x

-5x = 42/9

-5x = 4.6 (repeating 6)

x = -0.93 (repeating 3)

Hope this helps! ;)

Choose the pair of events that is mutually exclusive.​
barxatty [35]

Answer:

even numbers greater than 50 and prime numbers greater than 50

Step-by-step explanation:

An event can be considered as mutually exclusive in probability and statistics when two sample propositions cannot be held as true by any means. Therefore, the pair that clearly illustrates a mutually exclusive event would be "even numbers greater than 50 and prime numbers greater than 50."

The only prime number that is even is 2, so even numbers over 50 would be divisible by 2, and then not prime.
