Answer:
first solve the volume of the rectangular prism
V = l x w x h
where l is the length
w is the width
h is the height
V = 7 x 4 x 2.5
v = 70 cu cm
then solve the volume of the box
v = e^3
v = 0.5^3
v = 0.125
number of cubes = 70 / 0.125
number of cubes = 560 cubes
Step-by-step explanation:
Start by listing this until you see that X+Y = 50
X can equal: 4,8,12,16,20,24,28,32,36,40,<u>44</u>
Y can equal: 1.5,3,4.5,<u>6</u>,7.5,9
So...
X=11
Y=4
so... 4 sandwiches were bought, and 11 drinks.
Hey there!
The answer is C
If you plug them all in for "y", that is the only one that works.
(There is a way to solve it, though, but it's timed so I figured I wouldn't take hours to explain, comment if you want me to explain it to you, though)
Have a good day :)
x=13 because you put all of them in an equation and set them equal to 180 bc that is how many degrees are in a triangle so it would be 6x+19+5x-15+3x-6=180 and then you solve the equation so it would be 14x-2=180 then you would add to to both side which would cancel out on the left and make 182 on the right then divide 182 by 14 and you get 13.
