Alex is building a rectangle fence around his yard. the total perimeter of the fence is 68 feet and the area of his yard is 240

Alisiya [41]

Let's call the length of the rectangular fence $l$ and the width of the rectangular fence $w$ .

Based on the information in the problem, we can make two equations, based on the formulas for perimeter and area:

$A = lw$

$P = 2l + 2w$

Now, let's substitute in the values we are given in the problem:

$240 = lw$

$68 = 2l + 2w$

Now, let's solve the system using substitution.

$240 = lw \Rightarrow \dfrac{240}{w} = l$

Solve for $l$ from the first equation

$68 = 2\Bigg( \dfrac{240}{w} \Bigg) + 2w$

Substitute this value into the second equation

$68 = \dfrac{480}{w} + 2w$

Simplify

$68w = 480 + 2w^2$

Multiply both sides of the equation by $w$

$2w^2 - 68w + 480 = 0$

Subtract $68w$ from both sides of the equation

$(2w - 48)(w - 10) = 0$

Factor

$2w - 48 = 0$ and $w - 10 = 0$

Use the Zero Product Property and solve both factors

$2w - 48 = 0 \Rightarrow 2w = 48 \Rightarrow w = 24$

$w - 10 = 0 \Rightarrow w = 10$

We are given two possible lengths. However, the funny thing is that both produce the same dimensions: 24 ft by 10 ft:

$w = 24 \Rightarrow 240 = l(24) \Rightarrow l = 10$

$w = 10 \Rightarrow 240 = l(10) \Rightarrow l = 24$

Thus, our answer is Choice C, or 10 feet by 24 feet.

You divide the numerator (top number) by the denominator (bottom number) and you should get a decimal now all you have to do is move the decimal point two places the right and you should get your answer

Solve 1/3x - 2/7x > 1/3

Ne4ueva [31]

Answer: x > 7

Step-by-step explanation:

Given:

$\displaystyle \frac{1}{3}x- \frac{2}{7}x > \frac{1}{3}$

Subtract:

$\displaystyle \frac{1}{21}x > \frac{1}{3}$

Divide both sides of the equation by $\frac{1}{21}$ :

$\displaystyle x > 7$

<u>What does this mean?</u>

This means the x is equal to all values greater than 7.

-> 7.432421, 7.5, 8, 250, etc
