y=5(-1/4) +6
y=19/4
Answer:

Step-by-step explanation:
Let
x = cost for one adult
y = cost for one child
z = cost for one senior.
<u>The Reid family:</u>
take 2 adults and 2 children and paid
that is
, so

<u>The Mghee family:</u>
take 1 senior, 2 adults and 1 child and paid
that is
, so

<u>The Griffiths family:</u>
take 1 senior and 3 adults and paid
that is
, so

You get the system of three equations:

From the first equation:

From the third equation:

Substitute them into the second equation:

Then

Hence,
the cost for one adult is 
the cost for one child is 
the cost for one senior is 
<u>The Linton family</u> takes 1 senior, 2 adults and 3 children and paid

Answer:
3/4
Step-by-step explanation:
in order to simplify divide the numerator and denominator by the greatest Common Factor or both numbers... in this case the numbers are 6 and 8
6: 1,2,3,6
8:1,2,4,8,
as you can see the GCF is 2... so you divide 6 by 2 nd 8 by 2
6/2= 3
8/2=4
since 6 in ur numerator the quotient is 3 so the number 3 goes on the top
3/4
Mean: 200
median: 175
mode: all values only appeared once, so there isn't one
range: 275
The mean would not change at all.
