Abox contains both cubes and five-sided pyramids. the total number of objects in the box is 17. the total number of sides for the cubes and pyramids is 95. how many cubes are in the box? 6

We have the equation s

x + y = 17 
4x + 5y = 95       where x = number of cubes and y = number of pyramids

multiplying the first equation by -4:-
-4x - 4y = -68  Add this to the second equation:-
y = 27
Plug this into the first equation;-

x + 27 =  17 

x = -10 

There must be an error in your question because you can't have a negative number of cubes!!

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
