The correct answer is: D) Subtracted like terms incorrectly
Step-by-step explanation:
Given
The terms 11.2y-7.4y need to be subtracted. But option b is to add them. We will add them and then solve the equation to see if its right.
So adding 11.2y-7.4y
Dividing both sides by 18.6
so by adding the terms instead of subtracting we get y=7.6.
this means that the error was adding 7.4y-11.2y instead of subtracting
The correct method will be:
Dividing both sides by 3.8
Hence,
The correct answer is: D) Subtracted like terms incorrectly

Answer:
1. .
2. .
3. .
4. .
5. .
Step-by-step explanation:
1. The product of the third power of a and the fourth power of b = .
The 'third power of a' means 'a to the power 3' and 'fourth power of b' means 'b to the power 4'.
2. Six less than three times the square of Y means .
Here, 'three times the square of Y' means 'product of 3 and Y to the power 2', and 'six less than' means 'subtract 6 from the expression'.
3. The sum of a and b increase by the quotient of b and a means .
Here, 'quotient of b and a' means 'b divided by a'.
4. Four times the sum of r and a increased by twice the different r and s means .
Here, 'increased by' means 'addition' and 'different r and s' means 'r minus s'.
5. Triple the difference of 55 and cube of w means .
Here, triple means 3 times. (Answer)
