Cole is studying employment trends. he found that 20% of the social workers he surveyed, or 45 social workers, work part time. how many social workers did cole survey altogether?
plz me

The total number of social worker doing part time work is 9  .

Step-by-step explanation:

Given as :

The percentage of social worker on which Cole surveyed = 20 %

I.e 20 % of the social worker

Or the number of social worker = 45

Let The number of social worker working part time = x

So, x = 20 % of the total social worker

I.e x = 0.2 × 45

∴ x = 9

So , out of total 45 social worker , the number of social worker working part time = 9

Hence The total number of social worker doing part time work is 9  . Answer

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
