Adam buys a box of stuff that weighed 6 3/8. if he buys box of fruit that weighed 7 2/5. what is the combined weight.
jolli1 [7]

Answer:

The combined weight is 13 31/40.

Step-by-step explanation:

Given:

Adam buys a box of stuff that weighed 6 3/8. if he buys box of fruit that weighed 7 2/5.

Now, to find the combined weight.

So, we change the mixed fraction to improper first:

Weight of box of stuff = 6\frac{3}{8}=\frac{51}{8}.

Weight of box of fruit  = 7\frac{2}{5}=\frac{37}{5}.

Then, by adding to get the combined weight:

\frac{51}{8}+\frac{37}{5}

=\frac{51\times 5+37\times 8}{40}

=\frac{255+296}{40}

=\frac{551}{40}

=13\frac{31}{40}

Therefore, the combined weight is 13 31/40.

The product of two consecutive even positive integers is 674 more than the sum of the two integers. Find the integers.
IrinaVladis [17]
2n(2n+2)=2n+2n+2+674\\
4n^2+4n=4n+676\\
4n^2=676\\
n^2=169\\
n=-13 \vee n=13
-13\not\ \textgreater \ 0

n=13\\
2n=26\\
2n+2=28

It's 26 and 28.
