Hi everyone! Actually, I need your help as I am stuck in these 3 questions -
i) 13 + 5 + [ 100 ÷ 10 + { 15 × 2 ( 13 - 9 ÷ 5-1 )}]
ii) { 18 ÷ 9 ( 4 - 2 ) + 5 }
iii) [ 297 ÷ 3 + { 4× 3 ( 20 - 36 ÷ 5 - 2 )}]
Answers
Answer:
Distributive property with variables
Multiply, or distribute, the outer term to the inner terms.
Combine like terms.
Arrange terms so constants and variables are on opposite sides of the equals sign.
Solve the equation and simplify, if needed.
