What is algebraic Expression?
Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
Given this, Peter figures he can build the entire tree house by himself in 20 hours. He figures that each additional friend who helps him would improve the time by 10%.
An algebraicexpression that determines the given condition is:
n – n(0.10)
=> n(1- 0.1)
=> n* 0.9
Since the above equation is for A friend and it's given there are four friends helping him.
Thus,
The final time is taken in building the tree house if 4 friends are helping:
=> n * 0.9^4
Where n is 20
=> 20 * 0.9^4
=> 13.122
Therefore, it will take 13.12 hours to build the tree house if 4 friends are helping.

Percentage of tax that need to be given = 5%
Then
Amount of tax that needs to be given = (5/100) * 13.75 dollars
= 13.75/20 dollars
= 0.687 dollars
= 0.69 dollars
So
The total amount that needs to be
paid for dinner including tax = (13.75 + 0.69) dollars
= 14.44 dollars
Percentage of tips that they both want to leave = 15%
Then
Amount of tips that need to be given = (15/100) * 14.44
= 216.6/100 dollars
= 2.17 dollars
So
The total amount that they should leave = (14.44 + 2.17) dollars
= 16.61 dollars
So they should leave a total of $16.61 in the restaurant.

if you assume that the month has 30 days and that the library opens at midnight, then
24 hours in a day
5 pm=12+5=17 hours
on wednessday=17-2=15 hours
wednessday=1/7 of week
so we find 1/7 of 30 which is 30/7=4 and 2/7
then subtract that from 30
30-4 and 2/7=25 and 5/7
ok so then we have
25 and 5/7 days is 17 hours and
4 and 2/7 days is 15 hours
so just multipy them and add
25 and 5/7 times 17=437.143 hours
4 and 2/7 days times 15 =64.2857
add
437.143+64.2856=501.429
so aprox 501.429
the real equation is

emember you can do anything to an equaiton as long as you do it to both sides
12x-4y=20
add 4y to both sides
12x+4y-4y=20+4y
12x+0=4y+20
12x=4y+20
minus 20 both sides
12x-20=4y+20-20
12x-20=4y+0
12x-20=4y
divide both sides by 4
12/4x-20/4=4/4y
3x-5=1y
3x-5=y
y=3x-5
