Answer:
Step-by-step explanation:
Givens
Let the first piece be x
Let the second piece 4x
Let the third piece = 5x
Total length = 40 inches.
Equation
x + 4x + 5x = 40 Combine
Solution
10x = 40 Divide by 10
10x/10 = 40/10
x = 4
Answer
The smallest piece (x) = 4
The middle piece 4x = 4*4 = 16
The largest piece 5x= 5 * 4 = 20
Let the unknown number be y.
We can list the equation out by the clues given.
5y + 12 = 52
Then solve this as simple algebra!
Shift +12 to the other side and be - 12
5y = 52-12
5y = 40
Shift x5 to the other side and be ÷5
y = 40 / 5
y = 8
Therfore the unknown number is 8.
To combine like terms, check if there are any terms just like the first one, and we see 6xy. 9xy + 6xy = 15xy. So that is one term. Now I would see if the second term has any terms like the first one, and we see -3y. So -3y + (-3y), we would get -6y. That means our polynomial is now 15xy - 6y, and because this has two terms, it is a binomial. Hope this helps. Please rate, leave a thanks, and mark a brainliest answer. (Not necessarily mine).

The answer is: $18.00
1. I multiplied $18.00 by 2. $18.00*2=$36.00
2. Multiply the discount of 15% to the total amount for two pairs of glasses. $36.00*0.15= $5.40.
3. Subtract the discount from the original price. $36.00-$5.40= $30.60.
4. So the final answer for one pair of glasses is $18.00.
Okay so we have to figure out what percentage passed first let’s add all the percentages
25%+15%= 40%
Now subtract that from 100%
100%-40%= 60%
So 60% of the class passed
Now let’s use x to represent the total number of people on the class
x•0.6= 24
Now solve for x
x= 40
There are 40 people in the class we figure this out my converting 60% to 0.6 and multiplying it by 40 and getting 24 which is correct
