X + y = 4
x - y = 0
------------add
2x = 4
x = 4/2
x = 2

x + y = 4
2 + y = 4
y = 4 - 2
y = 2

solution is (2,2)....so it contains one point <==

Scilla [17]

Answer:

(a). $\frac{33}{40}$ ; (b). <em>33 to 40 </em>

Step-by-step explanation:

Use "magic fraction" $\frac{Part}{Whole}$

<em>(a).</em> Distance covered by runner is 33 yards

Whole distance is 40 yards

The portion of the race that the runner has completed is

$\frac{33}{40}$

<em>(b).</em> The portion of the race that the runner has completed is <em>33 to 40</em>

on this american flag the width of the blue rectangle is 2/5 the width of the red and white stripes. What fraction of the area o

Gnesinka [82]

The area of the blue rectangle is 8/11 of the flag

<h3>Area</h3>

The area of a shape is the amount of space it occupies

The width is given as:

$Width = \frac 25$

<h3>Blue region </h3>

The blue region of the American flag has a dimension of 8 by 11 stars.

So, we have:

$8 : 11 = x : \frac 25$

Where x represents the length of the blue region.

Express the ratio as fractions

$\frac{8 }{ 11} = x \div \frac 25$

Multiply both sides by 2/5

$\frac{8 }{ 11} \times \frac 52= x$

$\frac{20}{ 11} = x$

Rewrite as:

$x =\frac{20}{ 11}$

The area is then calculated as:

$Area =\frac{20}{ 11} \times \frac 25$

$Area =\frac{40}{ 55}$

Simplify

$Area =\frac{8}{ 11}$

Hence, the area of the blue rectangle is 8/11 of the flag

Brand X costs $2.70 for 10 ounces. Brand Y costs 4 cents more per ounces. What is the cost of 11 ounces of brand Y?

Ksju [112]

Well you have to first find the constant of Brand X which would be 2.70/10 = .27. Brand Y is .4 more so that would be .31 per ounce. So then .31 x 11 = 3.41. The cost of 11 ounces of brand Y is $3.41.
