We know that there was $5 left over, so we can set up an equation to solve for the price per water bottle:

$50 - 10x = 5\\-10x = -45\\x = 4.50$

Each water bottle cost $4.50

Here is the answer
10+1/7/2
remember if a fraction has 3 levels figure out two of them first: 10+1/7÷2
10+1/3.5
multiply both sides of the fraction by 2 to make the denominator a whole number
10+2/7

Write the expanded form of the expression. <br> -1/2 (y - x) = ?

morpeh [17]

Answer:

The expanded form of the expression $-\frac{1}{2}(y-x)$ is $\mathbf{-\frac{1}{2}(y)+\frac{1}{2}(x)}$

Step-by-step explanation:

We need to write expanded form of the expression $-\frac{1}{2}(y-x)$

For expansion we will use distributive property of multiplication over addition

$a(b+c)=ab+ac$

Applying above rule:

$-\frac{1}{2}(y-x)\\=-\frac{1}{2}(y)-(-\frac{1}{2}(x))\\=-\frac{1}{2}(y)+\frac{1}{2}(x)$

So, the expanded form of the expression $-\frac{1}{2}(y-x)$ is $\mathbf{-\frac{1}{2}(y)+\frac{1}{2}(x)}$
