x = original amount
1/2x + 11 = 30 SUbtract 11 from both sides of the = sign
1/2x = 19 Multiply both sides by 2
x = 38
a = v/t Multiply both sides of the equation by 't
at = v Divide both sides by 'a'
t = v/a
A=pi r^2 Divide both sides by pi
A/pi = r^2 Sqrt both sides
sqrt(A/pi) = r Do you see how it is done? Can you do the third one?
A little ambiguous wording in this question...two answers:
1 kg/hr x 4 hr = 4 kg dough prepared in 4 hours (This is how much logan prepared in 4 hours)
Total prepared will be 4 kg (previously prepared)+ 4 kg prepared in 4 hrs = 8 kg in who know how many hours !
Distance is 6km
I had all of the calcs entered and tried to post it but the server crashed and it all went away. I do not like the new overhaul of the website...this has happened several times.....site used to auto save input, but it does not anymore.
Do you mean (445^2)^3 ?
Using Web2.0 calculator:
(7/4)(7^2)*(tan(180/7))^-1 = 178.0617097559035774 Note : I had to put the multiplication sign between the parens before tan to get it to work AND this is in DEGREES
-3 (x+2) = -3(x) -3(2) = -3x -6 distributive property of multiplcation
Original cost x (1- .27) = off season price
Use distributive propert first to get:
-3x - 6 = 7 Add 6 to both sides
-3x = 13 divide both sides by -3
x = - 13/3 = - 4 1/3
I don't think infinity is a number...it is more like a concept of a never ending parade of numbers....or space.
