Answer:
x<5
Step-by-step explanation:
x+4<1
x<+1-4(in this situation +1-4 is kinda like saying -4+1 so you add them)
{x<5}
(thanks and sorry and welcome)
Answer:
$6.50 per candle
Step-by-step explanation:
19.50 / 3 = 6.50
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
If I understand the problem correctly, here's the answer:
2 (3x+6) + 2 (2x+4)=94
6x+12+4x+8=94
10x+20=94
10x=74
X=74/10
X=37/5
