What is the length of side angle AB of parrellelogram ABCD ?
zavuch27 [327]

\boxed{x=4cm}

<h2>Explanation:</h2>

A parallelogram is a quadrilateral that has two pair of opposite sides and each pair measure the same. In order to illustrate this problem, see the figure below. Here we know some facts:

  • Side AB measures x cm
  • Side DC measures 4 cm

By definition, opposite sides in any parallelogram measure the same, so AB and DC are opposite, therefore:

\overline{AB}=\overline{DC} \\ \\ \boxed{x=4cm}

How many solutions is there to the system of equations? 2x + 3y = 11 -4x - 6y = -22
Step2247 [10]

Answer:

x = 4, y = -3

Step-by-step explanation:

{2x - y = 11

{x + 3y = -5

You can use the substitution method by solving for x in the second equation:

x + 3y = -5

Subtract 3y from both sides:

x = -3y - 5

Now, substitute this value for x into the first equation:

2x - y = 11

2(-3y - 5) - y = 11

Distribute:

-6y - 10 - y = 11

Add 10 to both sides:

-6y - y = 21

Combine like terms:

-7y = 21

Divide both sides by -7:

y = -3

Next, substitute this value for x into the second equation:

x + 3y = -5

x + 3(-3) = -5

Multiply:

x - 9 = -5

Add 9 to both sides:

x = 4

a pair of jeans originally cost $140 and are now on sale for 65% off. what is the sale price of the jeans
Andrei [34K]

Answer:

$49

Step-by-step explanation:

<u><em>Method 1</em></u><u><em>:</em></u>

100% - 65% = 35%

\frac{y}{140}: \frac{35}{100}

y · 100 = 35 · 140

100y = 4900

100y ÷ 100 = 4900 ÷ 100

y = 49

<u><em>Method 2</em></u><u><em>:</em></u>

\frac{y}{140}: \frac{65}{100}

y · 100 = 65 · 140

100y = 9100

100y ÷ 100 = 9100 ÷ 100

y = 91

$140 - $91 = $49
