Answer:

option a) 30 : 19

Step-by-step explanation:

$Length = 7 \frac{1}{2} = \frac{15}{2}\\\\Width = 4\frac{3}{4} = \frac{19}{4}$

Ratio of length to width:

$\frac{15}{2} : \frac{19}{4}$

$=\frac{\frac{15}{2}}{\frac{19}{4}}\\\\=\frac{15}{2 } \times \frac{4}{19}\\\\=15\times \frac{2}{19}\\\\=\frac{30}{19}\\\\30 : 19$

Step-by-step explanation:

2(.5n-3)=n-0.25(12-12n)

first you distribute whatever is on the outside of the parenthesis to the inside of the parenthesis

1n-6=n-3+3n

then you combine like terms and end up with

1n-6=-3+4n

add 6 to each side to get

n=3+4n

subtract 4n from each side to get

-3n=3

divide -3 from each side to get

n=-1
