Cheapstore= 600g 20% off the normal price of £5 Superstore= 600g plus extra 30% extra £5 which box of ceral has better value?

Answers

Answer:

The one from superstore

Step-by-step explanation:

We are to find the box if cereal that gives us the best value for our money.

We first calculate for cheapstore

We have 500 pounds divide through by 10 = 50p

Multiply 50 with 2

= 100p

= 1 pound

4 pounds = 600 grams

For superstore

Divide 600 g by 10

= 60g

Multiply with 3

= 60g x 3

= 180g

600+180 = 780grams

600grams/4pounds = 150g

780grams / 5 pounds = 156gtams

From here we concise that superstore box has best value

P=60

Step-by-step explanation:

P=2(l+w)

P=2(14+16)

P=2(30)

P=60

Perimeter of a rectangle with 16in length and 14in width is 60 in.

Perimeter of a rectangle = 2(l+b)

here l = length and b= width

Given : l= 16 in and b= 14 in

perimeter = 2(l+b)

= 2(16+14)

= 2(30)

=60 inches.

The perimeter of rectangle is 60 inches

Answers

Answer and Step-by-step explanation:

90 - 51 = 39.

Angle L is equal to 39, since angle M is equal to 51.

The angles are complementary, so they add up to 90, which is why we subtract 51 from 90 to get 39.

Five friends want to travel on a trip. The bus ticket price is $50 for each friend, and the rooms and meals for everyone will cost $850.

To pay for the trip, friends work in the local shop. Each of them is paid $5 per hour. If each friend works the same number of hours, how many hours must each friend work so that there will be enough money to pay for the entire cost of the trip?

Answer this pls I'm this accounts cousin help me

Answers

Answer:

Step-by-step explanation:

Okay so first you need to find out how much money it will cost in total.

$50*5

=$250

$250+$850=

$1,100

Now, $1,100 divided by 5

1,100/5

=220 hours

And there are 5 friends so divide the total amount hours by 5.

220/5

=44 hours

So you see, each friend will need to work 44 hours.

Answers

Hello,

First of all, relax and take a deep breath right before you start.

Alright, so algebraic word problems are tricky sometimes. I am glad I don’t have to do them much. Once you understand more or less what to do, you should be fine!

I would need an example problem if you have one.

If not, then remember that you have to work with what you know, which is what you can start with and what you need to end with.

For instance, a phone company sells phones at $900 each. For a family discount, after 2 phones are bought, each additional phone is $100 off.
Find an expression representing the phone company’s prices.
2*900 + (900x - 100x)

x represents how many additional phones were bought.

If a family bought 6 phones:
2*900 + (900x - 100x)
2 in front and 4 as x gives 6
That expression becomes

2*900 + [900(4) - 100(4)]
= $5000

I hope that helped!

3. The sum of two numbers is 17. The difference between the larger number and the
smaller number is 7. What is the value of the smaller number?


Answers

Answer:

5

Step-by-step explanation:

To solve this problem, we need to set up a system of equations. Let x represent the larger number and y represent the smaller number.

x + y = 17

x - y = 7

We can solve this system by adding them together. The y cancels out because y + (-y) = 0. After that, we solve for x

2x = 24          

x = 12              (Divide both sides by 2)

Now that we know the value of x, we can substitute it into one of our original equations to solve for y.

12 + y = 17      

y = 5                (Subtract 12 from both sides)

So, the smaller number is 5.
