Answer:
You can't find y in this way
Step-by-step explanation:
You should know the value of x
But you can say
Y=7x
<span>hypothesis :-
if x=30, then 3/4x+5≠20
let Q:- x=30 P:- 3/4x+5≠20
we need to prove if Q then P (Q →P)
proof :-
lets assume 34x+5=20 is true
now x=30
so
3/4(30)+5=27.5 ≠20
which is a contradiction

No your supposed to do the math and cancel out each nunber until you find y
Answer:
16
Step-by-step explanation:
Subtract the total he spent on bubblegum, from the total price spent on bubblegum and lollipops.
If you multiply the price for one piece of bubblegum by the quantity of bubblegum purchased, you will get the price for all the bubblegum, 0.50 * 5 = 2.50.
Subtract that from the total price “6.50” to get 4.00.
Then you can divide 4.00 by the lollipops price “0.25” to get the quantity of lollipops purchased, 4.00/0.25 = 16.
