Let's first start off with an equation to represent Celeste's budget:

Where:
'h' is the money in dollars that she needs to get her hair cut
'p' is the money in dollars that she needs to get her hair permed
'l' is the money in dollars that she needs for lunch
Now let's simplify this equation using the information that was given:

*This must be true since it is told that she needs $5 for lunch

*This is because the perm costs twice as much as the hair cut
Our new/updated equation is:

This is much easier to solve, let's rearrange and solve for 'p':



Therefore the perm costs $36
I hope this helps! Let me know if you have any further questions.
(3/7)-(1/14)=(6/14)-(1/14)=5/14
use LCD to get a like denominator, then just subtract
Ok
look at my picture below.
so the lowest number is minimum
the highest number is maximum
the average is mean. formula for average: sum of all no./no. of total number
median is the very middle no. the formula is: 1/2(n+1)
n=how many no.s there are.
If
is a zero of
, then we can write

for another polynomial

Note that
. Then

so that
