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
Step-by-step explanation:
by deleting
9y = -9
y = -1
6x - 4 = -10
6x = -6 then x = -1
Answer:
-2 and -6 is the correct answer
4 = y - 4
You need to add 4 on each side and you will get 8 which means that y is equal to 8.
4 = y - 4
+4 +4
8=y
