Answer:
x=8
Step-by-step explanation:
You would set them equal to each other to get 9x-13=6x+11.
You would them move 6x over so -6x on both sides. This would then get you 3x-13=11.
Then move the -13 over so add 13 to both sides to get 3x=24
Then get x by itself so divide by 3 to get x=24/3.
Then that simplified is 8
(-2.3)*4.7 would be equal to -10.81
Hi there!
Let's break this down:
Two times a number = 2n
Increased by 5 = + 5
is 15 - = 15
Total equation:
2n + 5 = 15
Solving:
2n + 5 = 15
2n = 10
n = 5
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Hi There!
Inequality:
v>83
This inequality says that
v is greater than $83.
Hope it helps!
Have an awesome day!

The answer is 21.
First you Add both AB and BC which is 10x +14. Then you put 64 into the equation. 10x+14=64. Subtract 14 from 64 which is 50. So 10x=50. Then divide 10 from 50. which would be x=5. So if you plug it in. It would be 21.
