because 320/4 = 80 mi/hr because it can not km or min and hr^2 would not make any sense
Answer:
X=4 Hope it helps Lol
Step-by-step explanation:
5*x-3-(21-x)=0
Step by step solution :
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
6x - 24 = 6 • (x - 4)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
2.1 Solve : 6 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
2.2 Solve : x-4 = 0
Add 4 to both sides of the equation :
x = 4
One solution was found :
x = 4
7.1 meters
First replace t with 1
-4.9(1)^2+12
(1)^2= 1
-4.9 times 1 is -4.9
12-4.9=7.1
Hence 7.1 meters
Hope this helps!
