Sagot :
"Example" so only one :)
But I'm nice so two.
Algebra.
Bella is 152.5 centimeters, Domini is 15 centimeters more than the height of Bella while Aerol's height is the height of bella multiplied by three minus the sum of Domini's height and Bella's height. What is the height of the three? Convert the height of the highest person into meters, and convert the height of the lowest person into millimeters.
let x = bella's height
let y = domini's height
let z = aerol's height
x = 152.5 cm
y = 152.5 cm + 15 cm
z = 152.5 x 3 - (y + x)
x = 152.5 cm
y = 167.5 cm
z = 135 cm
bella's height : 152.5 cm
domini's height : 167.5 cm
aerol's height : 135 cm
Heighest Height : Domini's , 167.5 cm = 1.675 meters.
Lowest Height : Aerol's, 135 cm = 1350 millimeters

Alexa has two apples, she gave one of it to Monika, and then she buys 10 more apples and gave all her apples equally into two persons, how many apples does each person receive?
2 - 1 = 1
1 + 10 = 11
11 / 2 = 5 and 1/2
So therefore, each person received 5 and 1/2 apples.

Mr. Botales is now thrice as old as his friend, Ms. Divant. Eight years ago, the sum of their ages was 40. How old are they now?
R: Let x = Mrs. Divant's age
3x = Mr. Botales's age
8 years ago Present
Mr. Botales 3x - 8 3x
Ms. Divant x - 8 x
E: (3x - 8) + (x - 8) = 40
S: (3x - 8) + (x - 8) = 40
3x - 8 + x - 8 = 40
4x - 16 = 40
4x = 56
--- ---- ⇒ x = 14; 3x = 42
4 4
A: Mr. Botales is 42 years old while Ms. Divant is 14 years old.
C: (3x - 8) + (x - 8) = 40
3x - 8 + x - 8 = 40
3(14) - 8 + 14 - 8 = 40
42 + 6 - 8 = 40
42 - 2 = 40
40 = 40
