If y = 2^2p−1 and z = p − 2, what is the value of y/z when p = 2.5?

Y=2^2-p Y=4-2.5 Y=1.5  X= p-2 X=2.5-2 X=0.5  Y/x= 1.5/0.5=3

11

step-by-step explanation:

32.50-7.50=25

225/25=11

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
