Solve each equation for x.
a. x−10=0
b. x/2+20=0
c. demanding dwight insists that you give him two solutions to the following equation:
(x−10)(x/2+20)=0
can you provide him with two solutions?

a) x = 10

b) x = -40

c) x = 10, -40

Step-by-step explanation:

a)

Taking 10 to the right hand side 10 becomes positive

So x = 10

b)

Taking 20 to the right hand side 20 becomes negative

Multiplying both sides by 2

So, x = -40

c)

Hence, x = 10, -40

So, two solutions can be provided

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
