Answer:

9-(x+y)

Step-by-step explanation:

9 would be before x and y for the equation bc it states 9 first

when it says x and y, it means that you add so x+y but you have to put in parentheses bc you have to find the value of x and y first

so lets say, for example, 9 decreased by x and y, x=3 and y=2

so the equation is 9-(x+y)

so then the new equation would be 9-(3+2)

so then 3+2 is 5 so you subtract 5 from 9 which would be 4

hope this helps

Find the perimeter of the window to the nearest hundredth. also how do you do it?

k0ka [10]

I am assuming the picture is of a stained glass window in the shape of a semicircle.

Answer: 7.71 feet.

Step-by-step explanation: The formula for finding the circumference of a circle is $\frac{1}{2}$ π × d + d.

The diameter is 3 feet. Substitute this into the equation:

$\frac{1}{2}$ π × 3 + 3.

Solve -

3.14 × 3 = 9.42

$\frac{1}{2}$ of 9.42 = 4.71

4.71+3 = 7.71

Round -

The answer is already rounded.

Hope this helped!~

Write the inequality (without solving)

Lesechka [4]

Answer:

$2.15f+4.6n\leq 150$

Step-by-step explanation:

She has a budget of $150, which means that she can spend no more than that amount. Therefore, use the less than or equal to symbol: ≤

Each folder is $2.15, so you are going to multiply: 2.15 × f

Each notebook is $4.60, so you will multiply: 4.6 × n

You want to know how many notebooks and folders you can buy for $150, so add the notebooks and folders.

Make the equation:

$2.15f+4.6n\leq 150$

:Done
