Answer: 2x - 5
Step-by-step explanation: 2x - 5 does not have anything in common, so therefore it can not be simplified. Then 3x - 3 can be divided by 3 because they have that in common. It can’t be 3x - 3 because it still contains one step left to be in its most simplified form.

Step 1: Define Systems
y = -4x + 1
11y = x + 146
Step 2: Solve for x
Substitution
Substitute in y: 11(-4x + 1) = x + 146Distribute 11: -44x + 11 = x + 146[Addition Property of Equality] Add 44x on both sides: 11 = 45x + 146[Subtraction Property of Equality] Subtract 146 on both sides: -135 = 45x[Division Property of Equality] Divide 45 on both sides: -3 = xRewrite/Rearrange: x = -3Step 3: Solve for y
Define original equation: y = -4x + 1Substitute in x: y = -4(-3) + 1Multiply: y = 12 + 1Add: y = 133y=4.8 (I'm so confused it isn't even funny)
Answer:
y = 1.6
Step-by-step explanation:
4.8/3=1.6
3*1.6=4.8
Answer:
[tex]y = 1.6[/tex]
Step-by-step explanation:
[tex]3y = 4.8[/tex]
Use inverse operations to solve this problem. Inverse operations is a method of solving a linear (and in some cases quadratic) equation. This method has one do the same operations to both sides such that it cancels out the operations done to the variable, and hence, it leaves one with the solution.
In this case, all one has to do is divide both sides by the coefficient of the varibale (y).
[tex]3y = 4.8[/tex]
÷[tex]3[/tex]
[tex]y = 1.6[/tex]

A student is solving -5+2x=15 find the students mistake and correct it
Answer:
correct students
-5+2x=15
2x=15+5
2x=20(divided by 2 both sides)
x=10
mistake students
-5+2x=15
-3x=15(divided by - 3 both sides)
x=-5
The required simplified value of the given expression is given as x = 10.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
Given expression,
-5 + 2x = 15
Now,
Adding 5 on both sides,
2x = 15 + 5
2x = 20
Divide by 2 into both sides
x = 10
Thus, the required simplified value of the given expression is given as x = 10.

1.) You toss 5 dimes. What is the probability that at least two dimes land on tails?
2.) King Francis decided to divide up his kingdom among his sons. He gave his first son one-eight of the villages he ruled over and one more village. The king gave his second son one-ieth of the remaining villages and two more villages. He continued like this, until he gave his seventh and youngest son one-eight of the remaining villages and and seven more villages. After that, all the villages in the kingdom had been passed on to his children. How many total villages are there in the kingdom?
Problem 1
Answer: 26/32-----------------------
Work Shown:
There are is 1 way to get 0 tails (aka 5 heads)
There are 5 ways to flip the coins so that exactly one coin shows tails and the rest are heads.
We have 1+5 = 6 ways of getting at most 1 tail. The phrasing "at most 1" means "1 is the largest number we can get".
There are 2^5 = 32 ways to flip five coins, so there are 32-6 = 26 ways of getting at least two tails. Note the events "getting at most 1 tail" and "getting at least 2 tails" are complementary events. One or the other must happen.
The probability of getting two or more tails is therefore 26/32.
========================================================
Problem 2
Answer: 56 total villages-----------------------
Work Shown:
We'll work our way backwards starting with the last (7th) son
x = number of villages left before the 7th son gets his share
x/8 + 7 = number of villages the 7th son gets
x - (x/8+7) = 7x/8 - 7 = number of villages left after the 7th son gets his share
This amount should be 0, so,
7x/8 - 7 = 0
7x/8 = 7
7x = 7*8
7x = 56
x = 56/7
x = 8
There are 8 villages left before the 7th son gets his share; this means he gets x/8+7 = 8/8+7 = 1+7 = 8 villages. Or you can note that if there are 8 villages left, and he's the last in line, then he gets the remaining 8.
Plugging x = 8 into 7x/8 - 7 leads to 0.
----------
y = amount of villages left before the 6th son gets his share
y/8 + 6 = amount of villages the 6th son gets
y - (y/8+6) = 7y/8 - 6 = amount of villages left after 6th son gets his share
We match up the x = 8 found earlier with this new expression and we solve for y. This is because x represents the number of villages leftover after the 6th son gets his share. After the 6th son gets his share, that leftover x is then handled for the 7th son as discussed above.
7y/8 - 6 = x
7y/8 - 6 = 8
7y/8 = 14
7y = 14*8
7y = 112
y = 112/7
y = 16
There are 16 villages leftover before the 6th son gets his share.
This means the 6th son gets y/8 + 6 = 16/8 + 6 = 2+6 = 8 villages.
----------
z = amount of villages left before the 5th son gets his share
z/8 + 5 = amount of villages the 5th son gets
z - (z/8+5) = 7z/8 - 5 = amount of villages left after 5th son gets his share
You can probably spot the pattern by now. We'll follow the same idea as before. Set 7z/8-5 equal to the 16 villages and we get
7z/8-5 = y
7z/8-5 = 16
7z/8 = 16+5
7z/8 = 21
7z = 21*8
7z = 168
z = 168/7
z = 24
There are 24 villages before the 5th son gets his share.
He gets z/8 + 5 = 24/8 + 5 = 3 + 5 = 8 villages.
------------
I'll do one more iteration
w = amount of villages left before the 4th son gets his share
w/8 + 4 = amount of villages the 4th son gets
w - (w/8+4) = 7w/8 - 4 = amount of villages left after 4th son gets his share
Set that equal to the previous value 24 and solve for w
7w/8-4 = z
7w/8-4 = 24
7w/8 = 24+4
7w/8 = 28
7w = 28*8
7w = 224
w = 224/7
w = 32
There are 32 villages before the 4th son gets his share.
He gets w/8 + 4 = 32/8 + 4 = 4 + 4 = 8 villages.
------------
The rest of the steps to find the other village counts will follow this template. You should find that each son gets 8 villages. There are 7 sons, so that means there are 7*8 = 56 villages total.
------------
It makes sense that the answer is some multiple of 8 because when taking 1/8 of the value leads to an integer. In other words, (1/8)*x is an integer.
Furthermore, it also makes sense that each son gets a multiple of 8 villages because if let's say the first son gets 9 villages (some non-multiple of 8), then 56-9 = 47 is not a multiple of 8. Plugging that into x/8+2 for the second son will lead to some non-integer result. So it's a bit nice that everything is a multiple of 8.
A stronger verification is shown in the table below. The table keeps track of how many leftover villages there are for any given son, whether its before or after they get their share. At the top we start with 56 and then slowly make our way down to 0 villages.

Given
[tex]Record = 24.49[/tex]
Required
Possible time to break the record
Since no option is given to select from. I will answer the question using inequalities
For her to break the record, she must swim at a time less than 24.49.
i.e. 24.48, 24.00, 23, 22.50, etc...
Represent the time with x.
