Answer:
k=3
Step-by-step explanation:
k-6=-3
k-6+6=-3+6
k=3
1)
Solving from system of equations:
x- amount of 1 cent stamps
y- amount of 33 cent stamps

2)
x- amount of 20 cent stamops
y-amount of 34 cent stamps
From system of equations:
Y-2= -3/4(x-6)
y=-3/4(x-6)+2
y=-3/4x+9/2+2
y=-3/4x+13/2
so for example if x=1 then y=5.76
or if x= 5 then y=2.75
10 1/2 ft=2x-18 in
convert ft to in--10 1/2ft=126 in
126=2x-18
2x=144
x=<em>72 inches or 6 feet</em>
First you have to figure out what IS 1/4 of 52, so all you need to do is put in your calculator 52 X .25 and get your answer
Then type in all of the four questions underneath into your calculator and chose the one that does NOT result in your original answer
