In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

Given here, let  mark has x= 10  pens and Kate has 5 times as many pens as Mark then kate would have 5x pens

therefore5x = 5×10

                    = 50 pens

Hence,  The pens that Kate has is equal to 50

The length of a rectangle is 5 less than 3 times the width. What is the length?

Perimeter = 46 inches
Write an inequality or equation, then solve.

Answers

Answer:

Let the width of the Rectangle be x inches

Then, length is (3x-5) inches

Perimeter of the Rectangle= 46 inches (given)

According to the above problem,

Equation :---- Perimeter=2(length+breadth)

2{(3x-5)+x}=46

2(4x-5)=46

(4x-5)=46/2=23

4x=(23+5)=28

x=28/4

x=7

So, length of the Rectangle is {(3×7)-5}=16 inches

and width is= 7 inches

Answer:

So, length of the Rectangle is {(3×7)-5}=16 inches

and width is= 7 inches
