To represent real - life situations into algebraic expression or equation, let a (1) LETTER be the unknown in the given situation. Use the (2)SYMBOL of the four fundamental (3) OPERATION to connect with other (4) CONSTANT to make an expression or an equation.
ASSESSMENT :
1 ----
1. FAITH BOUGHT 2 NOTEBOOKS WITH THE SAME PRICE AND A BALLPEN WHICH COSTS 12 PESOS.
A. 2n + 12
B. 2n - 12
C. 12n - 2
D. 12n + 2
2. YBONE IS 3 YEARS YOUNGER THAN HER SISTER. THE SUM OF THEIR AGES IS 25 YEARS.
A. n + 3 = 25
B. 3n = 25
C. n + n - 3 = 25
D. n + 3 - n = 25
3. FIND THE VALUE OF 3c+4b-12 if c = 8 and b=5.
A. 32
B. 28
C. 12
D. 8
Solution :
>>Substitute<<
3( 8 ) + 4( 5 ) - 12
((3 × 8) + (4 × 5))- 12
(24 + 20) - 12
44 -12
= 32
2 ---
4. 246 - 4n
5. 2688
Solution :
8 × 12 + 156 = n - 2436
96 + 156 = n - 2436
252 = n - 2436
n = - 2436 - 252 ( because the sign is same the operation will be addition)
n = 2688
