Answer:
11x + 12
Step-by-step explanation:
( 4x + 12 ) + 7x
Remove parentheses.
= 4x + 12 + 7x
Group like terms.
= 4x + 7x + 12
Add similar elements: 4x + 7x = 11x
= 11x + 12
Answer:
18
Step-by-step explanation:
I did my method that I was taught but if you do (-5) - (-2), you get 3. So you subtract 39 by the -21 to get 18.
3/4 is the simplified version of 6/8. How I got this is I know that 4 goes into 8 twice so you multiply by 2. Whatever you do to the bottom you do to the top so you will get 6/8.
Step-by-step explanation:
2x - 5 = 7
2x = 7 + 5
2x = 12
x = 12 / 2
x = 6
