Algebra and Linear equation in one variable

Translate into equation 9 times y yields 20 timey y less than 2

• 2+20y = - 9x

• 9x = 2- 20y

• 9x = 20 y -2

• 9x- 20 y = 2

If difference b/w perimeter of square and perimeter of rectangle is 24 . Length is x cm , breadth is y cm and side of square is 4 then write in expression in terms of x and y

Translate the statement into equation sum of perimeter of square whose side "a cm" and perimeter of rectangle is 2. If length is also "a cm" which is six of breadth

• a =5/7

• a=1/7

• a = 3/7

• a = 1/9

If perimeter of triangle is 15 times of perimeter of square if side of square is c cm . if three sides of triangle are x cm , 2cm and 10 cm Make the equation x in term of c
