Answer:
-7/6
Step-by-step explanation:
2x-8x+7=0
combine like terms
6x+7=0
subtract the 7 from both sides
6x=-7
divide 6 from both sides
-7/6 or -1 and 2/3
The simplest form of 35/56
is 5/8
H=-16t^2+56t+1, the airplane is shot up from a platform 1 foot above the ground, so 1= - 16t^2+56t+1, we solve this equation
(- 16t+56)t=0, (- 16t+56)=0 or t=o, - 16t+56=0, implies t =3.5s
so the answer is C)3.5 seconds
7/8+(−2/3) divided by 5/6
(7/8 - 2/3)/(5/6)
=(21/24 - 16/24) / (5/6)
= (5/24) / (5/6)
= 5/24 * 6/5
= 6/24
= 1/4
