Answer:
100
Step-by-step explanation:
1/10(3n+50)=35
3n+50=35*10
3n+50=350
3n=350-50
3n=300
n=300/3
n=100

Answer: i) Q=7*P ii) if P=5 => Q=35 iii) if Q=42 => P=6
Step-by-step explanation:
Q is directly prportional to P that means that
Q/P=k=const ( where k is the prportionality coefficient)
So k= 28/4=7
So i) Q= 7*P
ii) Q=5*7=35 if P=5 =>Q=35
iii) P=42/7=6 if Q=42 => P=6
Because the answer is 0.100 but you dont write the 2 ceros so the answer will finish being 0.1
