Answer:
5x= -15 I think
Step-by-step explanation:
You would have to solve the -6x+11=29 to find the value of x. To do so you would subtract the 11 from both sides leaving you with -6x=18. Then you divide that by -6 to find x. So x=-3. To find what 5x equals you would just plug in -3 as x and multiply 5(-3). Leaving you with -15.
If that is all it gives for the answer, then it is saying that x can be all numbers less than 3 except -2. So for interval notation it will be (-∞,-2),(-2,3). You also use the parenthesis instead of brackets because the number is not included in the answer.

Answer: The lowest common multiple of 12, 18, and 56 would be 504. Why? Well, see below for an explanation!
Step-by-step explanation: What is the lcm? Well, the lcm of two or more numbers is the lowest possible number that each number has in common as a multiple. Because we are dealing with large numbers, we can tell that the lcm will be a multiple of these numbers times at least 5. I multiplied all the numbers by 10, and it was too large and did not work. However, I backed up and tried 9.
56 x 9 = 504.
Why is this acceptable? Well, this is acceptable because I found that 504 can be divided by 12 and 18 both to get a whole number.
504 divided by 18 equals 28.
504 divided by 12 equals 42.
Using this principle, we will find that 504 is the lowest number that 12, 18, and 56 have in common.
Your final answer: 504 is the lowest common denominator. If you need extra help, let me know and I will gladly assist you.
Answer:
y = 40/3
Step-by-step explanation:
For greater clarity please write 3y-8/12 =y/5 as:
3y-8 y
-------- = ------
12 5
Cross-multiplying, we get:
15y - 40 = 12y
Combining the y terms yields 3y = 40, so that y = 40/3
