Answer:

(-4, 5)

Step-by-step explanation:

Hi there!
We are given the following system:
x+11y=51

3x+5y=13
And we want to solve it by substitution.
When we solve a system by substitution, we want to solve one of the equations for a variable; the variable should equal an expression containing the other variable. Then, we substitute that expression into the other equation as the variable we solve for, solve for that variable, and then use the value of the solve variable to find the value of the first variable

It's easier to solve for a variable if the leading coefficient in front of that variable is 1, like with x in the first equation (x+11y=51)
To solve this equation for x, we can subtract 11y from both sides.

x+11y=51

  -11y   -11y

_____________
x=51-11y
Now substitute 51-11y as x in 3x+5y=13:

3(51-11y)+5y=13

Multiply

153-33y+5y=13

Combine like terms.

153-28y=13

Subtract 153 from both sides

-28y=-140

Divide both sides by 28

y=5
Now substitute 5 as y in 51-11y to solve for x.

x=51-11y

x=51-11(5)
multiply

x=51-55

Subtract

x=-4

The answer is x=-4, y=5, or as a point, (-4, 5)
Hope this helps!

Answer: Andy covers all the walls of his kitchen using 6 rolls of a wallpaper.

To Find:

Number of rolls used per wall.

Solution:

Since, we know that the shape of a kitchen is a cuboid.

And a cuboid has total 6 faces, with 4 walls, one roof and one floor.

So, total number of walls in Andy's kitchen = 4

Now, it is given that he uses 6 rolls of wallpaper to cover 4 walls completely.

In order to find the number of rolls used per wall, we'll have to divide the total number of rolls used with the total number of walls.

Number of rolls used per wall =

                                                 So, 1.5 rolls are used to cover one wall.

The coordinates of the point (-1,0) after a translation 5 units to the right?

To get the coordinates of the point 1,0 after a translation 5 units to the right

The point's x-coordinate will rise by 5 units after being moved 5 units to the right, while the y-coordinate stays the same.

The starting point was at (-1, 0).

Increasing the x-coordinate by 5 units:

x-coordinate changed: -1 + 5 = 4.

Therefore, after being moved 5 units to the right, the point's new coordinates are (4, 0).

Answer:

The value of angle is 40 degrees

The value of angle P is 140 degrees

Therefore,

∠S = x + 15

∠p = 6x - 10

2(x + 15) + 2(6x - 10)  = 360

2x + 30 + 12x - 20 = 360

14x + 10 = 360

14x = 350

x = 350 / 14

x = 25 degrees

∠S = x + 15 = 25 + 15 = 40 degrees

∠p = 6x - 10 = 6(25) - 10 = 150 - 10 = 140 degrees

Answer:

x = 3; y = -4

Step-by-step explanation:

2(10x - 6y = 54) = ( 20x - 12y = 108)

4(-4x + 3y = -24) = ( -16x + 12y = -96)

Answer:

x=25.5

Step-by-step explanation:

x + 9.5 = 35

Using the subtraction property of equality, we can subtract 9.5 from both sides:

x + 9.5 - 9.5 = 35 - 9.5

x=25.5

The required solution of the given equation is given as x = 25.5.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given expression,
x + 9.5 = 35

Subtract 9.5 from both sides.
x = 35 - 9.5
x = 25.5

Thus, the required solution of the given equation is given as x = 25.5.

4x - 12 ≤ 32

⇒ 4x ≤ 44

⇒ x ≤ 11

Conversion a mixed number 8 1/2

to a improper fraction: 8 1/2=8×2+1/2=16+1/2=17/2

To find a new numerator:

a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2×3/3= 6/

3

b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8

c) Write a previous answer (new numerator 8) over the denominator 3.

Two and two thirds is eight thirds

Divide: 17/2×8/3=17/2×3/8=17×3/2×8= 51/

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 8/3 is 3/8) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - seventeen halves divided by eight thirds = fifty-one sixteenths.

Answer:

Agency A:  y = 12x

So Agency A pays a rate of $12 per hour

To create a straight line equation for the data in table, use  [tex]y = mx + b[/tex], where m is the slope and b is the y-intercept.

To find the slope m, take 2 points from the table and use the slope formula.

Let [tex](x_1,y_1)[/tex] = (3, 36)

Let [tex](x_2,y_2)[/tex] = (5, 60)

Slope formula: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{60-36}{5-3}=12[/tex]

Now use the point-slope formula to create the final equation:

[tex]y-y_1=m(x-x_1)[/tex]

[tex]\implies y-36=12(x-3)[/tex]

[tex]\implies y=12x[/tex]

Therefore, Agency A pays a rate of $12 per hour.

Agency B

From inspection, the function is a straight line.

Therefore we can use the straight line equation [tex]y = mx + b[/tex],

where m is the slope and b is the y-intercept.

From inspection, we can see that the line crosses the y-axis at (0,20).  Therefore, the y-intercept is 20.

[tex]\implies y=mx+20[/tex]

Taking 2 points on the line and using the slope formula to find the slope m:

Let [tex](x_1,y_1)[/tex] = (0, 20)

Let [tex](x_2,y_2)[/tex] = (3, 50)

Slope formula: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{50-20}{3-0}=10[/tex]

Therefore, the final equation is:  [tex]y=10x+20[/tex]

Therefore, Agency B pays an initial fee of $20 plus a rate of $10 per hour.

The segments AC, CB, and AB can form a triangle, and the statement is true.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Given that AC=9 cm, CB= 8cm and AB=15cm

The segments AC, CB, and AB satisfy the triangle inequality, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

AC + CB = 9cm + 8cm = 17cm, which is greater than AB = 15cm.

Similarly, AC + AB = 9cm + 15cm = 24cm, which is greater than CB = 8cm. CB + AB = 8cm + 15cm = 23cm, which is also greater than AC = 9cm.

Therefore, the segments AC, CB, and AB can form a triangle, and the statement is true.
