Q: 3.8y - 4.7 + 3.8y + 17.5
7.6y+12.8
Thank you so much :)
To solve the expression 3.8y - 4.7 + 3.8y + 17.5, we can combine like terms. Like terms are terms that have the same variable and exponent.
First, let's group the like terms together:
(3.8y + 3.8y) + (-4.7 + 17.5)
Next, let's add the like terms:
7.6y + 12.8
So, the simplified expression is 7.6y + 12.8.
If you have access to a calculator, you can simply input the original expression and it will perform the calculations for you. Otherwise, manually combining like terms step by step is a reliable way to solve such problems.
