Please help its a test. explain and select all statements that are true

B &D are Correct

B explanation: The variable is the 3, as the 3 is the amount per ride but we don’t know how many rides so you would multiply the unknown (x) by the 3, so this answer would be correct.

D explanation: if you replace the four with the x for both they both equal $28.

this can be solve using the formulaP = rghwhere P is the total pressurer is the densityh is the heightg is the acceleration due to gravity
fist solve the total pressureP = 1.5 bar + 1 barP = 2.5 barP = 250,000 Pa
P = rgh250,000 = (997)(9.81)hh =25.56 m
