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

12=24-y <br><br><br>help me pleaseee​
vitfil [10]

Answer:

y=12

Step-by-step explanation:

12=24-y

step 1

subtract each side by 24

24-24 cancels out

12-24=-12

now we have

-y=-12

we now have to divide by -1

-1/-1=1

-12/-1=12

so we can conclude that y=12

Write 560% as a decimal and as a mixed number
vekshin1
560% as a decimal = 5.6
(move the decimal points 2 spaces to the left.)

560% as a mixed number = 5 3/5
(divide 560 by 100; 100 goes into 560 5 times so 5 will be your whole number and since you have 60 left you divide 60 by 100; 60/100 can be reduced to 3/5 if you divide the numerator and the denominator by 20)

hope this helps :)
