Answer:

7-56n

Step-by-step explanation:

By using the distributive property you multiply the 7 to the 1 which equals 7. Then you distribute the 7 to the -8n which gives you -56n becaus emultiplying a negative and a possitive gives you a negative.

The required solution is -56n+7.

It is required to find the solution.

What is algebra?

A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.

Given:

Rearrange terms

7(1 - 8n)

=7(-8n+1)

Answers

Answer: Choice A) $0.20

=======================================================

Explanation:

The store bought the batch for $100, and sold that same batch for $150. The profit of the entire batch is 150-100 = 50 dollars.

Divide this over 250 to get 50/250 = 0.20 dollars.

Their profit is $0.20 per pastry (ie 20 cents per pastry).

-------

You can think of it like this

50 dollar profit = 250 pastries

50/250 dollar profit = 250/250 pastries (dividing both sides by 250)

0.20 dollar profit = 1 pastry

That last equation tells us one pastry yields a profit of $0.20 or 20 cents.

Answer:

$0.20

Step-by-step explanation:

If the purchased is $100 for 250 pastries, then 1 ipastry at purchase is:

$100=250

    ?  = 1

1×100/250 = $0.40 ( at purchase)

Then when resold, the profit is:

if 250 pastries= $150

1 pastry=?

$150× 1/ 250= $0.60

s0, the profit will be $0.60 - $0.40 = $0.20

Four friends buy cinema tickets using this offer.

Cinema tickets
Buy 3 tickets and get a tickets free
They each pay £6.15
How much does a ticket cost

Answers

Answer:

Step-by-step explanation:

The cost of one ticket will be  £8.20

Explanation

Suppose, the cost of one ticket is  

As the offer says "buy 3 tickets and get a ticket free" , it means they actually need to pay for 3 tickets.

So, the total cost of 3 tickets  

Each of four friends pay £6.15 , so the total amount they pay  

=£6.15*4=£24.60

Thus, the equation will be .....

=3x=24.60

=x=24.60/3=8.20

 So, the cost of one ticket will be  £8.20
