Restaurant 1 : y = 7k + 39
restaurant 2 : y = 2k + 44

7k + 39 = 2k + 44
7k - 2k = 44 - 39
5k = 5
k = 5/5
k = 1

y = 2k + 44
y = 2(1) + 44
y = 2 + 44
y = 46

Dinner would cost $ 46 at either restaurant if Lina's lobster weighed 1 kilogram.

What is 7/2 as a mixed number ​
kompoz [17]

Hello! :)

Answer:

\huge\boxed{3\frac{1}{2}}

\frac{7}{2} as a mixed number:

Divide 2 from 7 and find the remainder:

7 ÷ 2 = 3 R 1.

An improper fraction in mixed form has the quotient as the coefficient, and the remainder over the fraction. Therefore:

\frac{7}{2} = 3\frac{1}{2}
