10) should be T= 13/4
You multiply both equations by 4 and the least common multiply of 4,2. Then 8 x 4 + 3 - 4t = 2 ( 5 x 2 +1 ) multiply 8 and 4 to get 32. Add 32 and 3 to get 35. Then you multiply 5 and 2 = 10 add 10 and 1 = 11 multiply 2 and 11 = 22 eventually ur equation should look like 35 - 4t =22 so you subtract 35 from 35 and 35 from 22 = -13 then you should have ur equation; -4t = -13 then you divide -4 by -4 = t so T = -13 /-4 but you simplify-13/-4 and switch the negative signs to positive ; 13/4
Sample space would be:
(H,H), (H,T), (T,T), (T,H)
Here I have used H for heads and T for Tails... first coin for penny second for nickel...ok
Did you understand???
240 drops. you take 8x1/8=1ml so you have 8 8ths times 30 to give you 240 drops for 30ml test tube
Lets say cookies = x and days = y.
2x times y = 15.
8x times y = 45.
A 120 watt light-bulb is a 0.120 kilowatt light bulb.
In one hour, it uses 0.120 kilowatt-hour of energy.
If electrical energy costs $0.20 per kilowatt hour, then that light bulb costs
(0.120 kilowatt-hour / hour) x (0.20 dollar / kilowatt-hour) =
(0.120 x $0.20 / hour) =
$0.024 / hour = <span>2.4¢ per hour </span>
