Problem 1
Solution:
x = (13 - 3) × (10-3) × 1500
= 10 × 7 × 1500
= 70 × 1500
= 105000
Answer:
Php 105000.00
Problem 2
x = (12 × 8) + [(8 × 7) ÷ 2]
= 96 + [56 ÷ 2]
= 96 + 28
= 124
124 cm²
Problem 3
x = 130.56 ÷ 12.8
= 10.2
10.2 cm
Problem 4
x = 23.8 × 18.4
= 437.92
437.92 m²
Problem 5
x = (2.5 x 2) ÷ 2
= 5 ÷ 2
= 2.5
2.5 m²
