Which two simple machines are being used in the diagram

Answer: Lets call the number x

decreased means subtraction.  If x is decreased bt 23% then the result is

x-23%(x)  =  x-(23/100)x    or x-.23x

x-.23x=539

.77x=539

x=539/.77

x=700

check:  700-.23(700)=539

           700-161=539

           539=539

           Our answer is correct

19. x=62.55

20. x=1.75

Step-by-step explanation:

19. x = 62.55

20. x = 1.75

Answer:

40%

Step-by-step explanation:

As a Fraction your answer would be [tex]\frac{48}{120}[/tex].

However we are looking for it as a percentage.

In order to calculate, this you can simply find 10%, and 5% of 120.

10% = 12

5% = 6

48 is divisible by 12, therefore 48 / 12 = 4  

Giving you your answer which is 40%.

Answer: - 1/x or [tex]-\frac{1}{x}[/tex]

Step-by-step explanation:

(-3x^2 /3 ) * (4x^3 / 4)

=> - (3x^3 / 4) * (4x^3 / 3)

=> - (x^2 * 4) / 4x^3

=> - (x^2 / x^3)

=> - 1/x or [tex]-\frac{1}{x}[/tex]

The product of the two numbers will be -6.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the two numbers are (-3x2/3) and (4x3/4).

To find the product of (-3 * 2/3) and (4 * 3/4), we first need to simplify each expression:

(-3 x  2/3) = -2

(4 x 3/4) = 3

Next, we multiply the two simplified expressions:

-2 x 3 = -6

So, the product of (-3 * 2/3) and (4 * 3/4) is -6.

Answer:  The y-intercept of y = -1/2x -1  is (0,-1)

The y-intercept of y = 1/4x -4  is (0,-4)

The attachment shows the graph of these equations.

Step-by-step explanation:

Both equations are in slope-intercept form. y = mx + b

The constant, b, is the y-intercept.

The y-intercept of y = 1/2x -1  is (0,-1)

The y-intercept of y = 1/4x -4  is (0,-4)

On a graph, the y-intercept can be found by finding the value of y when x=0. This is the point at which the graph crosses through the y-axis.

Given:

y=-1/2x-1 and y=1/4x-4

For Finding the y- intercept put x= 0 we get

y = -1/2(0) -1

y= 0- 1

y= -1.

For Finding the y- intercept put x= 0 we get

y=1/4(0)-4

y= 0- 4

y= -4

Answer:

90 pages in 10 hours :)

Answer:

90 pages

Step-by-step explanation:

First, you need to find the unit rate of how many pages he can read.

So, you divide 18 pages by 2 hours = 9 pages per hour.

Then, you multiply 9*10 hours to find out how many pages he will read in 10 hours.

You get 90.

Answer:

x = 8     y = 8

Step-by-step explanation:

Multiply 2nd equation by -3 to get -6x - 3y = -72

Now  4x + 3y = 56

         -6x - 3y = -72

         -2x      =  -16

            x = 8

Substitute x = 8 into the 2nd equation

2(8) + y = 24

16 + y = 24

y = 8

Check:  Substitute the values into the 1st equation

4(8) + 3(8) = 32 + 24 = 56  So we have the correct values for x and y

Answer:

[tex]\%Tip = 13.04\%[/tex]

Step-by-step explanation:

Given

[tex]Tip= \$31.29[/tex]

[tex]Bill = \$208.60[/tex]

Required

Determine the percentage of the tip

First, we calculate the amount paid

[tex]Amount = Tip + Bill[/tex]

[tex]Amount = \$31.29 + \$208.60[/tex]

[tex]Amount = \$239.89[/tex]

The percentage of the tip is then calculated using:

[tex]\%Tip = \frac{Tip}{Amount} * 100\%[/tex]

[tex]\%Tip = \frac{31.29}{239.89} * 100\%[/tex]

[tex]\%Tip = \frac{31.29* 100}{239.89} \%[/tex]

[tex]\%Tip = \frac{3129}{239.89} \%[/tex]

[tex]\%Tip = 13.04\%[/tex]
