Answer:
first we will collect like term
2x-x+3x+4y+7y
4x+11y
there fore the answer is <u>4x+11y</u>
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.
<span>It is calculated as follows:
1.446x10^9/6.025x10^4=0.24x10^5=2.4x10^4. Therefore, the answer is 5.) 10^5</span>
