1. $9.00
2. Sorry, I don't understand this problem
3. Ally Cat because it is $1 cheaper
To work out the estimate cost you need do 200 * 5=$1000
then I used a calculator and the actual answer is $895
It would be: 12/75 = 4/25
So, your answer is 4/25
Hmm....
I know that the first answer is a coin, but I'm not too sure about the second one.
Answer:
x=2y-8
We use the substitution of x in the second equation
2*(2y-8)+3y= -2
4y-16+3y=-2
7y-16= -2
7y= -2 +16
7y=14
y=14Ș7
y=2
so x= 2*2 -8
x=4-8
x=-4
the solution is (x,y)=(-4, 2)
