9/12 chose Friday or Saturday. That reduces to 3/4. Which is also 75%. Hope that helps.
So baically
reresent
s=number of studne tickes bouthgt
a=number of adult tickets bought
300 tickest sold
total=300
a+s=300
value=rate times number of peple
student value=4s
adults value=10a
total value=1950
4s+10a=1950
a. system of equations are
s+a=300
4s+10a=1950
b. solve
s+a=300
4s+10a=1950
a+s=300
multiply by -4
-4s-4a=-1200
add to other eqaution
4s+10a=1950
<u>-4s-4a=-1200 + </u>
0s+6a=750
6a=750
divide 6
a=125
subsiute
s+a=300
s+125=300
subtract 125
s=175
a. s+a=300
4s+10a=1950
b. solution above
175 students
125 aduls
at most is either that number or less
so x<=72 would be the inequality
The answer is (-160) because you need to plug in the numbers for the equation 6 times
Answer is
Step-by-step explanation:
in y =mx+b form its y=2/5x + the y
