Help me me me i need help to get 100

45 pounds

Explanation:

Each cupcake is 0.45 pounds

They are asking for the weight of a hundred

So Multiply

0.45*100

So since its multiplying by base 10s

A easier way is to count the zeros and move the decimal place to the right (positive) to the amount of 0s

So 100 has 2 0s

Now 0.45

Move 2 decimal paces to the right  

45

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
