Mary has an office-supplies budget of $150 for

tatyana61 [14]

Part a)

The inequality that represents the number of folders f and notebooks n she can purchase is $2.15f+4.60n\leq 150$

Part b)

The graph is attached in figure.

Step-by-step explanation:

Part a)

Total budget of Mary = $150

Price of each folder = $2.15

Price of each notebook= $4.60

Let f represent folder and n represent notebooks the inequality will be:

$2.15f+4.60n\leq 150$

We are using less than or equal to (≤) because the budget is 150. the total price should be less than or equal to 150.

So, inequality that represents the number of folders f and notebooks n she can purchase is $2.15f+4.60n\leq 150$

Part b)

Graph the inequality 2x – 3y = 12

We need to graph the inequality but in the given question the inequality sign is missing.

Considering less than equal to (≤) sign

2x – 3y <= 12

The graph is attached in figure below.

devlian [24]

Answer:

I'm gonna say maybe 10..... yah 10

here's why

Answer:

In can pick in 10 ways.

Solution:

John has green, red, yellow, purple, orange, and blue paint = total 6 colours

he wants to have 4 different colours in the painting.

But in those 4 colors green is must, it should always be there.

So except green we have total 5 colours (red, yellow, purple, orange, and blue) from which we can pick any 3 colors(as green will be one in four colours).

Then we can choose 3 colours from 5 colours in x ways.

x ways = = \left(\frac{5 !}{3 !(5-3) !}\right)=(3!(5−3)!5!)

=\left(\frac{5 !}{3 ! \times 2 !}\right)=(3!×2!5!)

=\frac{5 \times 4 \times 3 !}{3 ! \times 2 !}=3!×2!5×4×3!

=\frac{5 \times 4}{2}=25×4

=\frac{20}{2} = 10=220=10
