EB Activity B:
Directions:
Match column A with column B to make the algebraic expressions or equations
correct
Example: If thrice a number is increased by 11, the result is 35.
3n + 11 =35
Column B
A 2n-7 =15
B. n=7y
Column A
1. If twice a number is decreased by 13.
the result is 9.
2 Seven less than twice a number is 15.
3. The difference between two-thirds of a
number and one-sixth of the same number
is seventy 75
4. The average of 6 numbers is 15. The
average decreases by 1 when the number
is added.
C. A=b/2, B=c12, C= 0/2
D.n-2
5. A is half of B.B is half of C. C is half of D.

6. Kevin is n years old now. Represent his
age 2 years ago.
F. 2/3n- n/6=75
7. Jose weigh m kilograms. Aries weigh
4 less than the weight of Jose. How
heavy is Aries algebraically?
G.y=2.12
8. Express algebraically the number of kilograms in
y pounds. (1 pound= 2.12 kg)
H.26 +x=14
9. Express the number of weeks in terms of y days.
