T) -7x+10y=20. M) -3x+y=-2 - ,
2(8x-5y)=35(2) -1(x+y)=-6(-)

-7x+10y=20. -3x+y=-2
16x-10y=70. -x-y=6

9x=90. -4x=4
[x=10] [x= -1]

-7(10)+10y=20. -3(-1)+y=-2
-70+10y=20. 3+y=-2

Assume that price is an integer variable whose value is the price (in US currency) in cents of an item. Assuming the item is pai
cestrela7 [59]

Answer:

Change = (Paid*100) - Price

Step-by-step explanation:

First of all we need to know the relation between 1 dollar and 1 cent in order to express everything in the units required in the question.

We know that 1 dollar = 100 cents, so the amount paid for the item with single dollars has to be multiplied by 100 to express its value in cents.

Paid_{cents}=Paid_{dollars}*100

Now that we have everything in cents, we can make the subtraction:

Change_{cents} = Paid_{cents} -Price_{cents}

Replacing the value in cents we get:

Change = (Paid*100) - Price

The answer is 2^12 = 4096.

With 12 spins, first there are 2 branches, then 2*2, then 2*2*2, ... In the end it's 2^12
