Solving for (3-8y) x (-2.5)
This expression involves the distributive property and multiplication of a binomial by a constant. Let's break down how to solve it step-by-step:
Understanding the Distributive Property
The distributive property states that multiplying a sum by a number is the same as multiplying each addend in the sum by the number and then adding the products.
In our case, we have:
(3 - 8y) x (-2.5)
We can distribute the -2.5 to both the 3 and the -8y:
(-2.5) x 3 + (-2.5) x (-8y)
Performing the Multiplication
Now, we simply multiply:
-7.5 + 20y
The Solution
Therefore, the simplified expression for (3-8y) x (-2.5) is -7.5 + 20y.
This answer can be written in different forms, such as:
- 20y - 7.5 (Rearranging the terms)
- -7.5 + 20y (Keeping the original order)
Remember that the expression can't be further simplified unless we have a specific value for 'y'.
