What is the percent decrease of 80 to 64
devlian [24]
The amount of decrease is  (80 - 64)  =  16

The fraction of decrease is the fraction of the original amount that disappeared.

That fraction is      (16 / 80)  =  1/5  =  0.2

To change a decimal to a percent,
move the decimal point 2 places that way ==> .

                             0.2  =  20%

Solve this question ​
ryzh [129]

Answer:

80

Step-by-step explanation:

Initial ratio:

Teachers to students

1 : 15

Ratio after:

Teachers to students

3 : 40

The number of students did not change, so we can make the students of the initial ratio and the students of the ratio after the same.

1 : 15 =  8 : 120

3 : 40 = 9 : 120

120 units = 1200

1 unit = \frac{1200}{120} =10

Initial teachers = 8 units = 8*10=80

What is the solution of the system of equations? 6x-2y = 4 -9x+3y = 12
katrin2010 [14]

We will have the following:

First, we solve both equations for y, that is:

6x-2y=4\Rightarrow-2y=-6x+4\Rightarrow y=3x-2

&

-9x+3y=12\Rightarrow3y=9x+12\Rightarrow y=3x+4

From this we can see that they are parallel lines, that do not share any common points, so there is no solution for the system.
