Write an algebraic expression for each item. Use X for the variable.
1.a number added to 15
a. 15 + x = b. 12 + x = c.xy + 15 =
2. thrice the number subtracted from 25
a.25 - 3x= b. 25 - 3x = c.0.3 -25x=
3. 5 more than twice a number
a.5* x = b.2x + 5 = c. 2 + 5x =
4.8 less than 5 times the number 8
a. 8x-5 = b.5x -8 = c.x * 5 + 8 =
5. a number times the sum of the number and 4
a x(x+ 4) b.x*4 c.x 4*X

Answer 1) :-
→ a number added to 15
Let the number is x .
so,
→ (x + 15) = (15 + x) (a) (Ans.)
Answer 2) :-
→ thrice the number subtracted from 25
Let the number is x .
so,
→ Thrice of x is subtracted from 25 = (25 - 3x) (a) (Ans.)
Answer 3) :-
→ 5 more than twice a number .
Let the number is x .
so,
→ 5 more than twice of x = (2x + 5) (b) (Ans.)
Answer 4) :-
→ 8 less than 5 times the number
Let the number is x .
so,
→ (5x - 8) (b) (Ans.)
Answer 5) :-
→ a number times the sum of the number and 4
Let the number is x .
so,
→ x(x + 4) (a) (Ans.)
