Answer:

1/4 - (2/5 + (1/3 - (3 - 7/2) - 1/4) - 2/15)

= 1/4 - (2/5 + (1/3 - (6/2 - 7/2) - 1/4) - 2/15)

= 1/4 - (2/5 + (1/3 - (-1/2) - 1/4) - 2/15)

= 1/4 - (2/5 + (1/3 + 1/2 - 1/4) - 2/15)

= 1/4 - (2/5 + (4/12 + 6/12 - 3/12) - 2/15)

= 1/4 - (2/5 + (7/12) - 2/15)

= 1/4 - (2/5 + 7/12 - 2/15)

= 1/4 - (24/60 + 35/60 - 8/60)

= 1/4 - (51/60)

= 15/60 - 51/60

= -36/60

= -3/5

What is the simplified form of the ninth root of x times the ninth root of x times the ninth root of x times the ninth root of x

Ksivusya [100]

Since you are working with exponents and roots you would add the exponents together. The ninth root of x is equal to x^(1/9) and since you are using it four times your answer would be x^(4/9).

Your cell phone company Offers you a choice between two promotional deals you can either get 500 free text messages with the cha

ollegr [7]

Answer:

The number of messages that will cost same both plans is <u>1000</u>.

Step-by-step explanation:

Given,

For 1st offer:

Total number of messages = 500

Charge of each message after 500 messages = $0.10

For 2nd offer:

Total number of messages = 400

Charge of each message after 400 messages = $0.20

We need to find out the number of messages can be sent for equal cost of both plans.

Solution,

Let the number of messages be 'm'.

So For 1st offer:

Total cost 'c' is equal to fixed cost for 500 messages plus charge of each message multiplied with number of messages.

framing in equation form, we get;

$c=500+0.10m$

Again for 2nd offer:

Total cost 'c' is equal to fixed cost for 400 messages plus charge of each message multiplied with number of messages.

framing in equation form, we get;

$c=400+0.20m$

Now the question said that the charge would be the same.

So we can say that;

$500+0.10m=400+0.20m$

On combining the like terms, we get;

$500-400=0.20m-0.10m\\\\100=0.1m\\\\$

Now using multiplication property, we will multiply both side by '10' and get;

$100\times 10=0.1m\times10\\\\1000=m$

Hence The number of messages that will cost same both plans is <u>1000</u>.
