Granite is a one of the most common igneous rock. Its used in building materials and making statues.
Step-by-step explanation:
If 30% were perfect, 70% were not perfect. So we know that 70% of the total number of photographs is 210.
p(70/100)=210 multiply both sides by 100
70p=21000 divide both sides by 70
p=300
So there are 300 photographs in all.
5x+15-6+7x
15-6= 9.
5=7= 12
12x+9 .
