Answer 1

Answer:

Step-by-step explanation:

Dear Student,

Here is the solution of your asked query:

a) Let the number be x.2 times a number=2xSo 2 times a number increased by 3=2x+3

b) Twice a number=2xTwice a number decreased by 7=2x−7

c)Let the first number be x.Another number is 3 more than first numberso another number = x+3so twice the sum of a number and another number=2(x+x+3)

d) Half of number=x2Half of number added to 12=x2+12e) 3 times a number=3x3 times a number subtracted from 8=8−3xa) Let the number be x.2 times a number=2xSo 2 times a number increased by 3=2x+3b) Twice a number=2xTwice a number decreased by 7=2x-7c)Let the first number be x.Another number is 3 more than first numberso another number = x+3so twice the sum of a number and another number=2x+x+3d) Half of number=x2Half of number added to 12=x2+12

e) 3 times a number=3x3 times a number subtracted from 8=8-3x

Answer 2

Here a condition is given in the question, we have to frame an algebraic expression for the same.

Condition given: Two times a number increased by three.

Let the number be x

So, two times the number = 2x

increased by three means we have to add 3

So, the algebraic expression will be 2x + 3
