Answer:
x = , y = 6
Step-by-step explanation:
5x + y = 7 → (1)
20x + 2 = y → (2)
Substitute y = 20x + 2 into (1)
5x + 20x + 2 = 7
25x + 2 = 7 ( subtract 2 from both sides )
25x = 5 ( divide both sides by 25 )
x = =
Substitute this value into (2) and evaluate
20( ) + 2 = y
4 + 2 = y , so
y = 6

Answer:
Yes maybe.
Step-by-step explanation:
Well basically if we find the volume of 20 pieces of candy in all, that would be= 20*0.8= 16 cu.inches
And then if we find the volume of the square based pyramid, that would certainly be= 3.6*3.6*4 that is 51.84
Then lastly, if we do, 51.84 ÷16 the final answer will be 3.24. Which might actually be the answer as the pieces of candy certainly can't pass the limit 20 according to me.

So there is 65 yards and one yard is 3 feet so you multiple 65 by 3 which is 195 . Then you divide by 4 as you have to see how many four foot pieces can be cut which you end up with 48.75 which means that you can have 48 four foot pieces. So since you have 48 four foot pieces you multiply 48 by 4 and you have 192 and if you subtract 195 which is how many feet there is in the 65 yards you get three feet and that is how much of the rope that is left over.
