PLEAS ANSWEE Sally and Joan were able to dust the house in 3 hours together. It takes

Joan 10 hours to finish the same job alone. Without help, how long

would it take Sally to finish the same job ?

14hrs

Step-by-step explanation:joan=10hrs

                                           joan+sally=3hrs

representing joan and sally's time taken in fractions 1/10+=1/3

1/3-1/10=7/30

7/30 by 60min(in an hour)

=14hrs

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
