To answer this question we will have to keep the following two points in mind:
#1. The <u>sum</u> of a number with another number means to <u>add </u>the given two numbers.
#2.<u> Twice</u> means to <u>multiply by 2.</u> In other words it means to double.
Therefore, "twice the sum" would mean to multiply the sum by 2.
Now, in our question we will have, "the sum of y and 9 would be:
and twice this sum would be: ![2(y+9)](https://tex.z-dn.net/?f=%202%28y%2B9%29%20)
Thus, "twice the sum of y and 9" is: ![2(y+9)](https://tex.z-dn.net/?f=%202%28y%2B9%29%20)
Answer:
i think quadratic equation is the answer.
18.24 pounds on each shelf because the weight divided by the amount of bags would be .96 pounds per bag. And then the total amount of bags divided by the amount of shelves would be 19 so 19x.96 pounds is 18.24 on each shelf

Step-by-step explanation:
<u><em>Girls for English:</em></u>
20 + English + 12 = 36
English + 32 = 36
English = 36-32
English = 4 (For girls)
<u><em>Total for Science:</em></u>
12+7 = 19
<u><em>Total for English:</em></u>
25 + English + 19 = 70
English + 44 = 70
English = 70-44
English = 26 pupils
