The correct answer would be: 6x+5y=3. I am not entirely sure, but that's what I believe is the correct answer.-Hope this helped!
James= 14. James +Kevin = 30
30-14= 30
14
----
16
therefore Kevin is 14 years old
8x + 7 + 2x + 23 = 180
10x + 30 = 180
10x = 150
x = 15
H= (2pier^2)/ 2pier all subtracted by s so the last equation from the picture.
Hope it helps!
Answer:
Step-by-step explanation:
Objects that float on water have densities less than the density of water; those that do not float on water have densisties greater than the density of water:
Float on water: d < 0.0361 lb/in³ (where d denotes denisity)
Do not float on water: d > 0.0361 lb/in³
