Between the first two steps we see ...

  15(x-\boxed{^})=25\\\\15x+30=25

Applying the distributive property to the first equation and comparing to the second, we see that ...

  -15\boxed{^}=30\\\\\boxed{^}=\dfrac{30}{-15}=-2

The number in the box should be -2.

Simplify the quotient 4.5 x 10^3/9 x 10^7 . Write your answer in scientific notation. Show your work.
astra-53 [7]
4.5*10^3/9*10^7=4.5/9*10^3*10^7=0.5*10^3*10^7. a^b*a^c=a^(b+c), so 10^3*10^7=10^(3+7)=10^10. 0.5*10^10=5*10^9, since we want to write in scientific notation where the leading number is bigger than one and smaller than 10.
