A woman bought some large frames for $10 each and some small frames for $5 each add a closeout sale if she bought 20 frames for

vampirchik [111]

Answer:

The quantity of large frames is 7

The quantity of small frames is 13

Step-by-step explanation:

Given as :

The price of each large frames = $ 10

The price of each small frames = $ 5

The total number of both frames bought = 20

The price for both the frames = $ 135

Now,

Let the quantity of large frames = L

And The quantity of small frames = S

So , According to question

The total number of both frames bought = 20

Or, The quantity of large frames + the quantity of small frame = 135

Or, L + S = 20 ......A

And $ 10 L + $ 5 S = $ 135 ................B

Or, $ 10× ( L + S ) = $ 10× 20

Or, $ 10 L + $ 10 S = $ 200

( $ 10 L + $ 10 S ) - ( $ 10 L + $ 5 S ) = $ 200 - $ 135

Or , ( $ 10 L - $ 10 L ) + ( $ 10 S - $ 5 S ) = $ 65

Or, 0 + 5 S = 65

∴ S = $\frac{65}{5}$

I.e S = 13

So, The quantity of small frames = S = 13

Put the Value of S in eq A

So , L + S = 20

Or, L = 20 - S

Or, L = 20 - 13

∴ L = 7

So, The quantity of large frames = L = 7

Hence The quantity of large frames is 7

And The quantity of small frames is 13 Answer

What does each equation have in common

Leona [35]

The equations have operations, variable, an equal sign in common.

<h3>What is an Equation?</h3>

An equation is a mathematical expression that contains an equals symbol.

As per the definition, the equation contain operations, variable, an equal sign. That means whatever be the equation then it must contain operations, variable, an equal sign.

So, all the equations have operations, variable, an equal sign these three things in common.

For example: 4a+b=0

What is the length of SA?<br> 1.89 ft<br> 2.43 ft<br> O<br> 3 ft<br> 7 ft

Brums [2.3K]

Incomplete Question, Figure is not there the required figure is attached below.

Answer:

The Correct option is third one 3 ft.

Therefore length of SA is 3 ft.

Step-by-step explanation:

Given:

BS = 10 ft

BT = 9ft

TC = 2.7 ft

TS || CA

To Find:

SA = ?

Solution:

Basic Proportionality Theorem:

Basic Proportionality Theorem States that "If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio".

Here, TS || CA ......Given:

$\dfrac{BS}{SA}=\dfrac{BT}{TC}$ ...Basic Proportionality Theorem

Substituting the values we get

$\dfrac{10}{SA}=\dfrac{9}{2.7}\\\\SA=\dfrac{27}{9}=3\\\\\therefore SA =3\ ft$

Therefore the length of SA is 3 ft.
