x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Answer:

\huge\boxed{x=1,\ y=2\to(1,\ 2)}

Step-by-step explanation:

\left\{\begin{array}{ccc}3x+4y=11\\x-2y=-3&\text{multiply both sides by (-3)}\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}3x+4y=11\\-3x+6y=9\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\ \ \ \ 10y=20\qquad\text{divide both sides by 10}\\.\qquad\qquad\boxed{y=2}\\\\\text{subtitute it to the second equation:}\\x-2(2)=-3\\x-4=-3\qquad\text{add 4 to both sides}\\\boxed{x=1}

Dovator [93]

Answer:

Yes, the graph makes it appear as if sales increased three folds.

Step-by-step explanation:

The graph presented by the advertising company is misleading, as it attempts to exaggerate the effect of its advert on sales. This can be attributed to the scale which is isn't uniform.

Last year sale was about 137000 and it grew to 150000 as a result of advertisement.

But from the bar chart, it seems there was three times increase in sales.

The length of a suitcase is 36 inches . The diagonal of the suitcase is about 51 inches . What is the width of the suitcase ,rou
Mrrafil [7]

<u>Given</u>:

The length of a suitcase is 36 inches.

The diagonal of the suitcase is about 51 inches.

We need to determine the width of the suitcase.

<u>Width of the suitcase:</u>

The width of the suitcase can be determined using the Pythagorean theorem.

Thus, we have;

d^2=l^2+w^2

where d is the diagonal, l is the length and w is the width.

Substituting the values, we get;

51^2=36^2+w^2

Squaring the terms, we have;

2601=1296+w^2

Subtracting both sides by 1296, we get;

1305=w^2

Taking square root on both sides, we get;

36.12=w

Rounding off to the nearest inch, we get;

36=w

Thus, the width of the suitcase is 36 inches.
