Remember that you can do anything to an equation as long as you do it to both sides except divide by zero
so you can add like terms like this
you can add similar things like 1+3 and m+2m and m^2+2m^2 but not unlke things like 1+m or m+m^2
so m+2m=1m+2m=3m so
r-4+6r=3+8r
use commutative property to move numbers around (a+b=b+a)
group like terms
r+6r-4=3+8r
add like terms
1r+6r-4=3+8r
7r-4=3+8r
subtract 7r from both sides
7r-7r-4=3+8r-7r
0r-4=3+1r
-4=3+r
subtract 3 from both sides
-3-4=3-3+r
-7=0+r
-7=r
r=-7
Answer=63 pictures
Jennifer=4/5*Luisa
Jennifer=28
Substitute '28' for Jennifer
28=4/5*Luisa
divide both sides by 4/5
35=Luisa
Luisa has 35 pictures on her camera
35+28=63
I = PRT....rearrange
I / PR = T
I = 360
P = 1800
R = 10% = 0.1
I/PR = T
360 / (1800*0.1) = T
360 / 180 = T
2 = T...so it would take 2 years

Here, we area provided a cone with:
- Radius = 48m
- Height = 68 m
We have to find the volume of the cone in feet³, and we are given that 1m = 3.2808ft
<h3><u>Ⳙ⳽ⲓⲛⳋ ⳨ⲟⲅⲙⳙ</u><u>ⳑɑ</u><u>:</u></h3>
The volume of a cone is equal to one third of the volume of a cylinder having the same base radius and height ,i.e:
