Answer:

(2, 1 )

Step-by-step explanation:

y = 6x - 11 → (1)

- 2x - 3y = - 7 → (2)

Substitute y = 6x - 11 into (2)

- 2x - 3(6x - 11) = - 7 ← distribute parenthesis and simplify left side

- 2x - 18x + 33 = - 7

- 20x + 33 = - 7 ( subtract 33 from both sides )

- 20x = - 40 ( divide both sides by - 20 )

x = 2

Substitute x = 2 into (1)

y = 6(2) - 11 = 12 - 11 = 1

solution is (2, 1 )

Answer:

The weight of box and pocking material $=13$ pound

Step-by-step explanation:

Let the weight of box and packing material $=x$

weight of package $=192$ pounds

total weight $=205$ pound

$x+192=205$

Subtract both side by $192$

$x+192-192=205-192\\x+0=13\\x=13$

Hence weight of box and packing material $=13$ pound

Answer:

You can round up to tenths, hundredths, thousandths, or tens, hundreds, and thousands. Some numbers, they have remainders when divided, so you would round them up to make them whole numbers or non-repeating decimals.
