The solution to the answer is as follows:

<span>x - y = 1...[1],
 
2x + y = 19...[2], {[1]+[2]}---> 3x = 30,
 
ie., x = 10. C is correct answer.

<h3><u>Answer:</u></h3>

Option: c is the correct answer.

The value of x is 10.

<h3><u>Step-by-step explanation:</u></h3>

We know that a solution of the system of linear equation can be obtained by the method of substitution.

Here we are given a system of equations as:

        x-y=11-------(1)

and  2x+y=19------(2)

We will get the value of y in terms of x from equation(1) and put that value in equation (2) to obtain the value of x as:

y=x-11

Now putting in equation (2)

2x+x-11=19

⇒ 3x-11=19

⇒  3x=19+11

⇒ 3x=30

⇒ x=10

( since on dividing both side by 3)

Hence, the value of x is:

10

Chris labels every lattice point in the coordinate plane with the square of the distance from the point to the origin (a lattice
stiv31 [10]

Answer:

4 times

Step-by-step explanation:

A lattice point may be defined as the point of intersection of two grid lines or more than two grid lines that is placed in a regularly spaced points arrays. This is called a lattice point.

In the context, Chris tries to label every lattice point in a coordinate plane with its square of distance from the point to its origin. The lattice points means that the numbers are both the integers. So for number 25, Chris has to label 4 times

i.e. (55),(-5,5),(5,-5),(-5,-5)

Randy is painting part of a wall, excluding the two corners shown in white. a gallon of white paint will cover 100 sqaure feet.
uysha [10]

Randy needs to purchase 1.49 Gallons of paint to cover 100 sq. feet wall.

What is the area of rectangle?

The area of a rectangle is the product of its length and width. That is,       A = l x w where l is the length and w is the width of the rectangle.

Here, Required Paint = 20 X \frac{37}{4} - 2 X \frac{1}{2}X6 X 6\\

                                   = 5 X 37  - 36

                                   = 185 - 36

                                   = 149

                                   = 1.49 gallons

Thus, Randy needs to purchase 1.49 Gallons of paint to cover 100 sq. feet wall.

Hello, can you please review attached and help me with the answer ?
Elis [28]

Answer:

<em>(a). P(x) = 8x - 112,000 </em>

<em> (b). $80,000 </em>

Step-by-step explanation:

(a). P(x) = R(x) - C(x)

P(x) = 50x - 112,000 - 42x

<em>P(x) = 8x - 112,000</em>

(b). P(24,000) = 8(24,000) - 112,000  = <em>80,000</em>

----------------------------------------

(a). <em>P(x) = 8x - 112,000</em>
