Answer:

Perimeter =20cm

Length =6

Breath = X

P= 2(l+b)

20 =2(6+x)

20=12+2x

20-12=2x

8=2x

x=8/2

x=4

Answer:

The Width is 4cm

The Area is 24cm²

Step-by-step explanation:

2(6cm+xcm)=20

12+2x=20

(collect like terms)

2x=20-12

2x=8

(divide both sides by the coefficient of x)

<u>2</u><u>x</u>=<u>8</u>

2 2

x=4cm is our width

so for the area our formular is L*B=6*4=24cm²

Help needed asap! Must be answered using interval notation!
Elina [12.6K]

In this case, we have a colored dot at -1 and a white dot at 3, then the interval notation for that graphed interval will be:

[-1, 3).

<h3>How to write the interval of values in the graph using interval notation?</h3>

First, remember that the symbols ( and ) are used for ends that do not belong to the interval.

For example, if our interval is 1 < x < 2

1 and 2 do not belong to the solution interval, thus, the solution interval is (1, 2).

While [ and ] are used when the ends belong. For example, in:

1 ≤ x ≤ 2

The interval notation is [1,  2]

And in:

1 < x ≤ 2

(1, 2]

And so on.

On the number line, the notation is:

  • Colored dot: the point belongs to the interval.
  • White dot: the point does not belong to the interval.

In this case, we have a colored dot at -1 and a white dot at 3, then the interval notation for that graphed interval will be:

[-1, 3).

The equation of a line is y = 2x + 3. What is the equation of the line that is parallel to the first line and passes through (2,
Masja [62]

Answer:

y = 2x - 5

Step-by-step explanation:

The slope for a parallel line is the same as the slope in the given equation.  Therefore the slope of the new line will be 2    m= 2

use that slope and (2, -1) to find b

-1 = 2(2) + b

-1 = 4 + b

-5 = b

Plug m and b into y = mx + b

y = 2x - 5

Rita earns $10 per hour. She puts 5% of her earnings in savings. Write inequality to find how many hours Rita must work to save
Rina8888 [55]

Answer:

Rita must work 50 days  to save at least $25.

Step-by-step explanation:

The amount Rita earns per hour  = $10

The saving percentage =  5%

So, the savings of Rita per hour =  5% of $10

⇒5% of $10  = \frac{5}{100}  \times 10  = 0.5

or Rita saves $0.5 per hour.

The amount she wants to save at minimum  = $25

So, let she works at the minimum of k Days.

⇒\textrm{The number of hours she has to work}  = \frac{\textrm{Amount she needs saving}}{\textrm{Amount saved in 1 hour}}

or, k = \frac{25}{0.5}  = 50

The number of hours she has to work  =  50 days

Hence,  Rita must work 50 days  to save at least $25.
