Answer:

Susan worked 22 hours and 30 minutes.

Step-by-step explanation:

You can solve this using either a proportion or just simple calculator inputs! I used the inputs :

191.25/8.50 = 22.5


but, if you wanted to use a proportion :

8.50/1 = 191.25/x

8.50x = 191.25(1)

8.50x/8.50 = 191.25/8.50

x = 22.5

and the .5 means half of an hour, which is 30 minutes, so, Susan worked for 22 hours and 30 minutes that week :)

In what ratio of line x-y-2=0 divides the line segment joining (3,-1)and (8,9)​
NISA [10]

Answer:

The ratio in which the line x-y-2=0 divides the line joining A(3,-1) and B(8,9) is in the ratio 2:3

Step-by-step explanation:

Let (x, y) be the coordinates of point of intersection.

Hence x=(a*8+1*3)(a+1) = (8a+3)/(a+1)

and

y = {a*9+1*(-1)}/(a+1)=(9a-1)/(a+1)

Since this point lies on the line x-y-2=0

Hence (8a+3)/(a+1)-(9a-1)/(a+1)-2=0

i.e. 8a+3–9a+1–2(a+1)=0

Or 8a+3–9a+1–2a-2=0

i.e.-3a+2=0

Hence a=2/3

hence the ratio in which the line x-y-2=0 divides the line joining A(3,-1) and B(8,9) in the ratio 2/3:1

i.e. 2:3

!!!! HELP!!! What is the solution to this system of linear equations?
earnstyle [38]

Answer:

(7, 3)

Step-by-step explanation:

get rid of the y by adding:

 x=-2

+x=16

then add the equalities:

2x=14

divide by 2:

x=7

then subsitute the x in to find y!

7+3y=16

3y=16-7

3y=9

y=3
