Since we are tutors from all over the US, and there are hundreds of books called algebra I, there is no way any of us could give an answer to this question.
Perhaps you could try posting a problem, and we can give you an explanation for the solution and you can get what you need from it?

because this is a five digit square, we are squaring a 3 digit number that ends in 6 and is less than 250*250, but greater than 200*200
our choices then are
226^2=51076
236^2=55696
the only one that meets the criteria of a so the number is 55696
a+b+c = 20

clear the parentheses:

add 5 to both sides:

subtract 5x from both sides:

convert 5x to a fraction

combine x terms:

multiply both sides by 3 to clear the denominator:

divide both sides by -13

let's break this apart into manageable pieces:
a fish was caught whos tail weighs 9 pounds.
Let the Tail (T) = 9 pounds
His head weighed as much as his tail and half his body,
Head (H) = T + 1/2 Body (B)
H=9+B/2
and his body weighs as much as his head and his tail.
B=H+T
B=H+9

how much does the fish weigh
since we know that the head =9+b/2, we can substitute into our second equation:
B=9+b/2+9
B=18+b/2
b-b/2=18
b/2=18
b=36
so the body weighs 36 pounds,
the head weighs 27 pounds
and the tail weighs 9 pounds
the fish (in total) weighed 72 pounds
That is certainly a whopper!

Since I don't know where you made your error, I can guess that either you forgot to distribute the negative sign in front of the (9+p)or you forgot to distribute the 2 to the (p+5), so:
using the distributive property we will clear the parentheses:
2(p + 5) - (9 + p) = -3
2p+10-9-p=-3
then combine like terms:
p+1=-3
subtract 1 from both sides:
p=-4

In order to solve these trig problems, you should remember:
sin^2X+cos^2X=1
and remember that
tan=sin/cos
cot=cos/sin
sec=1/cos
csc=1/sin
1. sin=(sqrt3)/4 then:
cos=(sqrt13)/4
tan=(sqrt3/sqrt13)
csc=4/(sqrt3)
sec=4/(sqrt13)
cot=(sqrt13)/(sqrt3)
2. cot=1/2 then:
sin=2/(sqrt5)
cos=1/(sqrt5)
tan=2
csc=(sqrt5)/2
sec=sqrt5
cot=1/2
3. csc=5 then:
sin=1/5
cos=(2sqrt6)/5
tan=1/(2sqrt6)
sec=5/(2sqrt6)
cot=(2sqrt6)
4. sec=5/3 then:
sin=4/5
cos=3/5
tan=4/3
csc=5/4
cot=3/4
5. cot=2 then:
sin=1/(sqrt5)
cos=2/(sqrt5)
tan=1/2
csc=sqrt5
sec=(sqrt5)/2

Ax+By=c
subtract Ax from both sides of the equation:
By=c-Ax
divide both sides by b
y=(c-Ax)/b

this is in its simplest form (no two numbers mutliplied together will give you x^2 + 4)

let the first angle = x
let the second angle =4x
let the third angle = x+4x-45
so when these are added together, they will total 180 degrees:
x+4x+x+4x-45=180
add 45 to both sides and combine like terms:
10x=225
x=22.5 degrees
so if the first angle =22.5 degrees, the second angle must = 90 degrees and the final angle equals 90+22.5-45 = 67.5 degrees.

First put this into y=mx+b format:
add 3x to both sides:
15y=3x-9
divide by 15:
y=(3/15)x-(9/15)
reduce fractions:
y=(1/5)x-(3/5)
your y intercept occurs when x=0:
y=-3/5, so the y-intercept is (0,-3/5)
the x intercept will be when y=0
0=(1/5)x-(3/5)
add 3/5 to both sides:
3/5=1/5x
multiply both sides by 5:
3=x, so the x intercept occurs at (3,0)

1. logbase8 8 = is it 1? This is correct.
2. logbase3(1/9) = -2?? This is correct
The first two problems seemed to be no problem for you, you simply put them into the same form and solved, so we can rewrite the following problems in the same form to see the answers as well:
3. logbase1/3 9= 27??? rewrite 9 as (1/3)^-2 so the problem is now:

4. logbase5 cuberoot25 = rewrite cube root of 25 as so the problem now reads:

5. logbasesqrt3 9 = rewrite 9 as

6. lne^3= = rewrite this as 3*lne (the lne=1) so, 3*1=3

if the cost is minimized, then it will equal zero:

divide both sides by 2:

factor:

x=-5 or 25
since we are talking about producing an item, we cannot produce negative items, so we can discard the -5 answer.
costs will be minimized if 25 units or more are produced.

A is 3 years older than B:
A=3+B
B is twice the age of C:
B=2C
so A compared to C is
A=3+2C
the sum of their ages is 30:
(3+2C)+(2C)+C=30
3+2C+2C+C=30
3+5C=30
subtract 3 from both sides:
5C=27
divide both sides by 5
C=27/5 or 5 and 2/5 years
so B is
2(27/5) =54/5 = 10 and 4/5 years
and A is 13 and 4/5 years
check:
10 and 4/5 + 13 and 4/5 + 5 and 2/5 = 30, so it is correct

if you think about slicing a cylinder lengthwise and unpeeling it, it would look like a rectangle, right? (roll up a piece of 8.5x11 paper and it makes a cylinder)
so the formula for the surface area will be length * width. the trick here is to remember that the length will be the height of the cylinder, and the width will be the circumference of the cylinder:
circumference = 2pi*radius
so the area = 2pi*radius*height
the volume is the area of opening to the cylinder * height

so the volume + surface area =

because everything is being multiplied (and not added or subtracted) you can take every cancellation opportunity:

so the (3*2) in the numerator cancels with the 6 in the denominator:

then the x in the numerator cancels with the x in the denominator:

then the (y^2*y) in the numerator will cancel with three of the Y's in the denominator:

First get rid of the denominator by multiplying everything by 5:

The key to simplifying radicals is to factor what is inside the radical

then pull out groups of numbers according to the index on the radical - if there is no index, it is by twos. In this case, we can only pull out a set of two "2"'s from the first radical sign. When you pull out the group represent it in front of the radical by one of it's members
example:

so your problem becomes:

then add anything that has the same radical:

Let n = the number of mugs purchased by the retailer
Let n-2 = the number of mugs available for sale (the retailer broke two)
Let (48/n) - the cost of each mug purchased by the retailer ($48 spent divided by the number of mugs)
If she sold each mug for a 3 profit
(3+(48/n)) is the sale price of each mug
(n-2)(3+(48/n)) = the total sales (the number of mugs sold*the price)
the total sales = cost + $22 profit
(n-2)(3+(48/n))=48+$22
