Question

19.The value of x in the equation

(1 Point)

(2 −1) +(−1) =(+2)(2x −1) +(x−1) =(x+2)​

Answer 1

Step-by-step explanation:

(2-1)+(-1) = (2) (2x-1) +(x-1) =(x+2)

→ 1+(-1) = (4x-2) +(x-1) =(x+2)

→ 1-1=5x-3=x+2

→ 5x-3=x+2

→ 5x-x=2+3

→ 4x=5

→ x= 5/4

Answer 2

Answer:

ANSWER

3, 15, 27, 39…….

a

n

=a+(n−1)d

a=3,d=15−3=12

n=54

a

54

=a+(n−1)d

=3+(54−1)×12

=3+53×12

=639

Term which is 132 more than its 54th term is – 639 +132 = 771.

a

n

=771

771=a+(n−1)d

771=3+(n−1)12

771=3+(n−1)12

64=n−1

n=65
