...plans to take a bath, but forgets to close the drain. The bath usually takes 10 minutes to fill and 12 minutes to empty. how long will it be before the bath is filled if Tara continues not to notice ...

...is x + 6 for one side and x + 6 for the other side. Added together we have x + 6 + x + 6 = 2x + 12 Adding the 4 sides together we get 2x ( the 2 short sides) + 2x + 12 (the long sides) we get 4x

12+2m=20-2m 12 + 2m = 20 - 2m 2m + 2m = 20 - 12 4m = 8 m = 8/4 m=2 4m = 8 m = 2 12+2m=20-2m 2m+2m=20-12 4m=8 m=2

factor 3m+12 3m + 12 3(m + 4)

...so we will add the equations to eliminate ‘y’. x-y=2 x+y=10 so add them together (x-y)+(x+y)=12 2x = 12 X= 12/2 = 6 subsitutue for 6+y=10 y=10-6=4 Answer X = 6 and Y = ...

4x - 2x + 1 = 5 + x - 7 1. Combine like terms on the left side of =4x-2x =2xNew left side is 2x + 12. Combine like terms on right side of =5 - 7 = -2New right side is x - 23. New problem is 2x + 1 = x

what is the surface area and volume for 14ft 12ft 3ft? homework If that is a right rectangular prism Volume =14*12*3 c.f. For the area here is the formula. Total area of right rectangular prism =2*A_b

How do solve the problem, if X=1/x and Y=1/y, solve 12/x-12/y=7? There are no solutions. x = 1/x multiply both sides by x: x^2 = 1 take the square root of both sides x = sqrt(1) this gives x = 1 or x

How do solve if X=1/x and Y=1/y, 12/x-12y=7 There are no solutions. x = 1/x multiply both sides by x: x^2 = 1 take the square root of both sides x = sqrt(1) this gives x = 1 or x = -1 similarly, y = 1
