Answer:
8 13/24
Step-by-step explanation:
42 2/3= 42 16/24
34 1/8= 34 3/24
42 16/24- 34 3/24= 8 13/24

A1/A2=b1/b2 is not equal to C1/c2
The rocket will take 9.25 seconds to return to ground
<em><u>Solution:</u></em>
Given that toy rocket is launched vertically upward from ground level with an initial velocity of 148 ft per second
<em><u>Height "h" after "t" seconds is given by equation:</u></em>
To find: time taken by rocket to return to ground
The time taken by rocket to return to ground is found by substituting h(t) = 0 in above equation
First take "t" as common term
Zero product property. The zero product property states that if a⋅b = 0 then either a or b equal zero. This basic property helps us solve equations like (x+2)(x-5) = 0
So for above equation we get,
-16t + 148 = 0
-16t = -148
t = 9.25
When t = 0 , the rocket would not left the ground. So ignore t = 0
So t = 9.25
So the rocket will take 9.25 seconds to return to ground
X 1 2 ----- + ---- = ------- so the common denominator will be 4(2x-1) 2x-1 4 2x -1 4x +2x-1 8 ----------- = --------- 4(2x-1) 4(2x-1) 6x-1 8 ---------- = -------- make the restriction for x so 2x-1 =0 ,result x=1/2 4(2x-1) 4(2x-1) so what mean that x not can being equal 1/2 6x-1=8 6x = 9 x= 9/6 x = 3/2
