What is algebra? How to use algebra in our daily lives?

Every time you need to problem solve a situation that involves money, time, distance, the perimeter of a fence or skate ramp, the volume of something, comparing prices when you shop, rent something - the cost versus time, other situations you are using algebra.

Step-by-step explanation:

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.

Step-by-step explanation:

Every time you need to problem solve a situation that involves money, time, distance, perimeter of a fence or skate ramp, volume of something, comparing prices when you shop, rent something - cost versus time, other situations you are using algebra

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
