Answer:

Expression representing number of text messages sent on Tuesday = 2x , where x = text messages sent on Monday

Step-by-step explanation:

Let number of messages sent on Monday = x

So, number if messages sent on Tuesday = 2 times x = 2x

Number of texts sent on Wednesday = 12 more than texts sent on Tuesday = 2x + 12

Number of texts sent on Thursday = Half the texts sent on Wednesday =   1/2 (2x + 12) = x + 6

Is this rational or irrational? If so why ?
xeze [42]
0.12 can be written as 12/100 or 3/25. It is very much a rational number as no square root is involved in the fractional form of the number.

For the class of 2013's prom Norman's dress shop sold cheaper dresses for $90 each and more expensive dresses for $140 each. The
Tema [17]

Answer:

Number of cheaper dresses sold  is 35

Number of expensive  dresses sold  is 15

Step-by-step explanation:

Given:

Cost of cheaper dresses = $90

Cost of  expensive dresses = $140

Total cost of  the dresses = $5250

To Find:

Number of cheaper dress = ?

Number of expensive  dress = ?

Solution:

Let

The number of  cheaper dresses be x

The number of  expensive dresses be y

(Number of cheaper dresses X cost of cheap dress) +  (Number of Expensive dresses X cost of  expensive dress)  =  $5250

x \times90 +y \times 140 = 5250=  $5250

It is given that the 20 more of the cheaper dresses than the expensive dresses is sold

So,

number of cheaper dress  =  20  +  number of expensive dress

x = 20 + y---------------------------------------(1)

(20+y) \times90 +y \times 140 = 5250 = 5250

(20 \times 90 +y\times 90) +y \times 140= 5250

1800 + 90y+ 140y = 5250

1800 + 230y = 5250

230y =5250 -1800

230y = 3450

y = \frac{3450}{230}

y = 15

Substituting y in (1)

x = 20 +15

x= 35

Help me find the answerr
notka56 [123]

Answer:

m∠3 = 24°

Step-by-step explanation:

By the theorem,

"Intercepted arc measures the double of the inscribed angle formed by two chords meeting at one point of the circle."

In the given picture,

∠3 is the inscribed angle subtended by the arc ED and is the intercepted arc.

Therefore, m∠3 = \frac{1}{2}m(\text{arc}ED)

m∠3 = \frac{1}{2}(48)

        = 24°

Measure of angle 3 is 24 degrees.
