N + N + 2n = 64 -- 4n 64 11 = 4 4

N + n + 2n = 64 -- 4n 64 11 = 4 4

 

Answer:

1. 24

2. 10

3. 14

4. 8

5. 16

Step-by-step explanation:

1. 4:8 = 12:n think of a variable na pwedeng i multiply sa 4 na ang sagot ay 12 (which is 3) then kapag nakuha muna multiply it sa 8 so 8×3=24 kaya ang sagot ay 24

2. 5n + 3n = 80 think of a variable na pwede i-multiply sa 5 at 3 na magiging sagot sa 80. since 5 at 3 yan pwede mo sita i add then add zero na lang so basically yung variable is 10 kase if wala yung zero you can multiply it by one.
