She would have to buy 4 packages because the LCD is 60

It should be 4 packages, with some mental math. 

4 * 20 = 80

4 * 15 = 60

Remember we still have 20 beads left over now. Add it to 60 and bam! You're done!

What is the graph of linear inequality 2y>x-2
pickupchik [31]

Answer:

Please refer to the attached graph for the graph of linear inequality:

2y>x-2

Step-by-step explanation:

Method to draw graph of inequality:

<u>1. First of all replace the inequality sign with equality.</u>

Now the equation is:

2y=x-2

Now, find point and plot them.

Let us put x = 0, we get y = -1. So one point is <em>(0, -1)</em>

Let us put y = 0, we get x = 2. So one point is <em>(2,0)</em>

Now, plot both the point and join with straight line on xy coordinate axis.

2. Now, try to find a random point and put in the inequality.

If the point satisfies the inequality shade the region moving from the line towards that point.

For example:

Taking a point (4, 2)

Putting in the inequality:

8 > 2-2 \\8>0

So, (4, 2) satisfies the inequality.

Now, shade the region moving from the line towards the point (4,2).

We get the shaded region as shown in the attached figure in the answer area.

suppose someone tells you that she has a triangle with sides having lengths 2.6, 8.1 and 8.6 is this a right triangle? why or wh
yawa3891 [41]
By the converse of the Pythagorean Theorem, if 8.6 ^2 = 8.1 ^2 + 2.6 ^2 , then the triangle is right. 73.96 is not equal to 72.37 so the triangle is not a right triangle.

8.6^2 is greater than (8.1^2 + 2.6^2) which means that the triangle is obtuse.
The obtuse angle is opposite the 8.6 side.

George has $15. He tries to buy a movie ticket ($9.00), a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each) but
Ket [755]

Answer:

George doesn't have enough money because the total cost of what he wants to buy costs $16.48 and he has $15. This means he needs an extra $1.48 to be able to buy what he needs

Step-by-step explanation:

From the above question:

George has $15. He tries to buy a movie ticket ($9.00), a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each) but he does not have enough money.

Look at the numerical expression George used: 15 −( 9 + 2.65 + 1.35 + 2(1.74) )

Use the order of operations to simplify this expression.

Using the order of operations we have:

=$ 15 - (9 + 2.65 + 1.35 + 2(1.74) )

= $15 -( 9 + 2.65 + 1.35 + 3.48 )

=$ 15 - (16.48)

= $-1.48

George doesn't have enough money because the total cost of what he wants to buy costs $16.48 and he has $15. This means he needs an extra $1.48 to be able to buy what he needs

Step-by-step explanation:

The fundamental theorem of algebra states that if a polinomial has a degree n, therefore has n roots. To fidn these roots the use of complex number imay be necesary .

For the equation, degree is 3, so there are 3 solutions.
