answer:

she sends about 14 messages a day

step-by-step explanation:

using x as the total amount of texts your sister sends in a day

12 + x = 26

or

x = 26 - 12

all we really need to do now is solve the equation, ill be using the second one to help me explain this better!

x = 26 - 12

now word problems can get a little tricky sometimes but all we need to do is subtract to find out our answer

26 - 12

= 14  

x = 14 messages

and if you wanted to double check your answer, then you will using the first equation that we made!

12 + 14 = 26

true

( dont forget to replace the x for your answer 16 )

i hope this helps you! and if you need anymore help or if you need me to explain this better then feel free to comment! :)

Answer:

69.45 m to the nearest hundredth.

Step-by-step explanation:

I guees you want the length of one side.

A square has 4 sides of equal length and the area = s^2  where s = length of each side.

So the length of a side of a square of area 4823

= √(4823)

= 69.4478 m.

Length of the median CP
ehidna [41]

Given:

ΔABC \sim ΔDEF

To find:

The length of median CP

Solution:

In ΔABC,

AP = 12, BP = 12 and PC = 3x - 12

In ΔDEF,

DQ = 16, QE = 16 and FQ = 2x + 8

If two triangles are similar, then their median is proportional to the corresponding sides.

$\Rightarrow \frac{AP}{DQ} =\frac{PC}{FQ}

$\Rightarrow \frac{12}{16} =\frac{3x-12}{2x+8}

Do cross multiplication.

$\Rightarrow 12(2x+8)=16(3x-12)

$\Rightarrow 24x+96=48x-192

Add 192 on both sides.

$\Rightarrow 24x+96+192=48x-192+192

$\Rightarrow 24x+288=48x

Subtract 24x from both sides.

$\Rightarrow 24x+288- 24x=48x- 24x

$\Rightarrow 288=24x

Divide by 24 on both sides.

⇒ 12 = x

Substitute x = 12 in CP.

CP = 3(12) - 12

     = 36 - 12

     = 24

The length of median CP is 24.
