Answer:
a) 5s + 10a = 4500
s+a = 700
b) $2500
c) $1000
Step-by-step explanation:
a) Let students = s and adult = a
5s + 10a = 4500 -------1
s+a = 700 -------2
Using elimination metthod
Multiply eqn 2 by 5
5s + 10a = 4500
5s + 5a = 3500
Subtracting
5a = 1000
a =200
s = 700- 300= 500
b) if both tickets sell for $10 each
200*10 + 500*10 = $7000
Extra money that would have been made = 7000- 4500 =$2500
c) if s is $5 and a is $15
Tickets sold = 200*15 + 500*5 =$5500
Extra money made = $5500- $4500
= $1000
Let
x---------> represents Martin's sister's age
y--------> represents Martin's age
we know that
--------> equation
--------> equation
Substitute equation in equation
therefore
<u>the answer is</u>
Part a) An inequality that can be used to represent this situation is
or
Part b) the oldest age Martin's sister can be is years old
Answer:
1.33
Step-by-step explanation:
so mean is the average
so what you have to do is add the numbers for each person and then divide by the amount of numbers present. the question is asking for the difference so subtract the numbers for each from person.
mia's mean= 34.33
sophia's mean= 35.667
sophia-mia= 1.33

First get rid of the last set of () by doing distributive property with the - sign
x^2 + 2x -1 - x^2 + 2x -1
=4x - 2
