x = -2
Step-by-step explanation:
This is some simple Algebra
So it's 4x+16=-2
We subtract 16 from both sides
4x=-18
Sivide both sides by 4
X=-4.5
If you need more of an explanation I am happy to elaborate
54+9= 63 m = distance and time=35 sec hence, speed= 63/35=9/5=1.8 m/s
time taken to reach water surface= distance/speed=54/1.8=30 sec
-3 1/2= -7 / 2
-7 /2 /-5 /8
-7 /2 times - 8 /5
56 /10
Reduce 28 / 5
Answer. 28 / 5
