At sea level a box weights 40lbs at the top of mt. everest the same box will weigh

stay the same

Explanation:

consider the fact that yes the box will stay the same also that it is further from the earth there for being the same weight cause it still has enough gravitational pull for it to fall not float.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
