Answer:

Step-by-step explanation:

(Standard form is automatically in integers)

Multiply by 3 to take out the fraction

3y=2x+21

-2x -2x

-2x+3y=21

Standard form means Ax+By=C with positive A (usually--some people allow A to be negative).

Multiply by (-1)

2x-3y=-21

(Technically, that's the more correct answer, but since you don't have that choices, it's just the previous one.)

Beatrice built about 1/3 of a sandcastle. Linda built 4/7 of the same castle. What fraction of the sandcastle did they build tog

wlad13 [49]

Answer

Find out the what fraction of the sandcastle did they build together .

To prove

Let us assume that the fraction of the sandcastle they build together be x .

As given

$Beatrice\ built\ about\ \frac{1}{3}\ of\ a\ sandcastle.$

$Linda\ built\ \frac{4}{7}\ of\ the\ same\ castle.$

Than the equation becomes

$x = \frac{1}{3} +\frac{4}{7}$

L.C .M of (3,7) = 21

solving

$x = \frac{7 + 3\times4}{21}$

$x = \frac{19}{21}$

Therefore the fraction of the sandcastle did they build together be

$x = \frac{19}{21}$

Hence proved
