Answer: -a+5
First you combine like terms
a-2a equals -a
After that you can’t combine anything else
So the equation simplified is -a+5

Please help me answer the question in the picture!
Slav-nsk [51]

Answer:

x = 5 units.

Step-by-step explanation:

In a parallelogram. diagonals bisect each other.

This means $ \overline{CE} = \overline{BE} $.

$ \implies 15 - x = 2x $

$ \implies 15 = 3x$

$ \implies x = 5 $.

Therefore, the length of x = 5 units.

Which sequences are arithmetic? Check all that apply.
spin [16.1K]

Answer:

3)    18, 5.5, –7, –19.5, –32, …   sequence is in Arithmetic Progression.

5)     16, 32, 48, 64, 80         sequence is in Arithmetic Progression.

Step-by-step explanation:

If, a, b, c ,k, e ... is a given sequence.

Then the above sequence is in AP if b - a   =  c - b = k - c = ...

or, each term has same COMMON DIFFERENCE (d).

Here, take each sequence and check for the value of d.

1) –5, 5, –5, 5, –5, …

Here, 5 - (-5)  = 10,   -5 - 5  = -10

and 10 ≠ -10.  So the sequence is NOT in Arithmetic Progression.

2)96, 48, 24, 12, 6

Here, 48 - 96  = -48,   24 - 48  = -24

and -48 ≠ -24.  So the sequence is NOT in Arithmetic Progression.

3)18, 5.5, –7, –19.5, –32, …

Here, 5.5 - 18 = -12.5    ,  -7 - 5.5 = -12.5  ..

and -12.5 is the common difference.  

So the sequence is in Arithmetic Progression.

4)–1, –3, –9, –27, –81, …

Here, -3-(-1)  =  - 2     -9 - (-3)  = -6

and -2 ≠ -6.  So the sequence is NOT in Arithmetic Progression.

5)16, 32, 48, 64, 80

Here, 32 - 16 = 16    ,  48  - 32= 16  ..

and 16 is the common difference.  

So the sequence is in Arithmetic Progression.

A carnival costs $10.50 to enter plus an additional $3.50 per ticket for rides and food.
Wewaii [24]

Answer:

1.) $10.50 + $3.50n

2.) Replace the variable with the given number. In this case, the given number is 20.

n = 20

$10.50 + $3.50(20)

$10.50 + $70 = $80.50

So, the total cost to visit the fair is $80.50.

Expand.<br> If necessary, combine like terms.<br> (x – 5)2 =
grin007 [14]

To expand  you must first distribute (multiply) the 2 to the numbers inside the parentheses

2(x - 5)

(2 * x) + (2 * (-5) )

2x + (-10)

2x - 10

There are no like terms, therefore (x - 5)2 expanded is 2x - 10

Hope this helped!
