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.

One positive number is one-fifth of another number. The difference between the two numbers is 144, find the numbers.
liubo4ka [24]

Answer:

36, 180

Step-by-step explanation:

x = y/5, so y = 5x

y - x = 144

5x - x = 144

4x = 144

x = 144/4 = 36

y = 5x = 5*36 = 180

The two numbers are 36 and 180

Solve the system using elimination.
expeople1 [14]

Answer:

(- 9, - 9)

Step-by-step explanation:

Given the 2 equations

3x - 4y = 9 → (1)

- 3x + 2y = 9 → (2)

Adding (1) and (2) will eliminate the term in x

(1) + (2) term by term

(3x - 3x) + (- 4y + 2y) = (9 + 9)

0 - 2y = 18

- 2y = 18 ( divide both sides by - 2 )

y = - 9

Substitute y = - 9 into (1) or (2) and evaluate for x

(1) → 3x + 36 = 9 ( subtract 36 from both sides )

3x = - 27 ( divide both sides by 3 )

x = - 9

Solution is (- 9, - 9)
