Q2. Prove that lg30=-10
Q3. John ate some sweets. Carmen ate 5 more sweets than John. The toal amount of sweets eaten by Carmen and John is 15. Find the amount of sweets Daniel Ong eaten.
Q3:
Let john be “a”
Let Carmen be “a+5”
a + (a+5)=15
2a+5=15
2a=15-5
2a=10
a=5
John ate 5 sweets
Carmen a + 5,
5 + 5= 10
Therefore Carmen ate 10 sweets.
Daniel Ong is not stated.
