Answer:

70kg

Step-by-step explanation:

Firstly, because nothing else changed about the treasure chest apart from the amount of treasure when the mass increased, the difference in mass must be the mass of the 1/4 chest of treasure which was added.

712 - 498 = 214kg

Now that we know that 1/4 chest's worth of treasure has a mass of 214kg, we can multiply this by 2 to find the mass of 1/2 a chest of treasure (without the chest):

214 x 2 = 428 kg

We now know that since 1/2 a chest of treasure has a mass of 428kg, the difference between the mass of the chest AND treasure when it is half full must be the mass of the box:

498 (mass of chest and 1/2 chest worth of treasure) - 428 (mass of just 1/2 chest worth of treasure only) = 70kg (mass of chest only)

We can check this by using the other given mass as well. 214 x 3 = 642kg

This means 3/4 of a chest's worth of treasure only, has a mass of 642kg, meaning the extra mass in the 712kg must be the mass of the chest:

712 - 642 = 70kg

The chest has a mass of 70kg.

Hope this helped!

What you find 420% of 85 what are you looking for?​
muminat

Answer:

420% of 85 = 357

Step-by-step explanation:

85/x=100/420

(85/x)*x=(100/420)*x       - we multiply both sides of the equation by x

85=0.23809523809524*x       - we divide both sides of the equation by (0.23809523809524) to get x

85/0.23809523809524=x

357=x

x=357

Consider the following system of equations.
34kurt

Answer:

  D. The graphs of the equations intersect each other at two places.

Step-by-step explanation:

The definition of a solution of a system of two equations in two variables is a point where the graphs intersect. A system of equations having graphs that intersect each other will have as many solutions as there are intersection points. If the graphs intersect in two places, there will be two solutions.
