Can you solve it if I write the same thing like this ?

                   s    +    12
                 3s    -      8
                =========  


The piece on the left is
                                            s
                                          3s
                                      ====
                                          4s   .

The piece on the right is
                                           12
                                          -  8
                                        ====
                                             4  .

Write the pieces together again, and you have

                                   4s + 4

How can I solve this math equation?
alukav5142 [94]

Answer:

Graphing

Step-by-step explanation:

1) You can graph this equation by using y=mx+b. You can replace that equation with y=3x-1.

M=3

X=x

B=-1

On a graph you would down 1 since it's negative and make a point. Then you would put a 1 under the 3 to make it a fraction. 3/1. Then you would divide 1 by 3 (1 ÷ 3). Then you would go to the right 0.33 because it's positive, and the up 1. Then you would make a second point.

This would only give you one line which wouldn't give you an intersection.

The average cost of hiring is £520

The new increased cost of hiring is £800

Percentage increase is

What is the area, in square centimeters, of the trapezoid below?<br> 11.7 cm<br> 5.5 cm<br> 6.5 cm
Mrrafil [7]

Answer:

50.05 cm^2

Step-by-step explanation:

Ok so first lets find the area of the rectangle before finding the attached triangle. You have to imagine a line separating this shape into a triangle and rectangle.

The rectangle's size is 6.5x5.5=35.75 cm^2

The rectangle's size is 11.7-6.5 to get the base length, which is 5.2

The height is 5.5

So it's 5.2*5.5/2=14.3 cm^2

14.3+35.75=50.05 cm^2
