Answer:

17n+11

Step-by-step explanation:

Formula For Perimeter Of Rectangle: 2(Length) + 2(Width)

                                                            Length = 3.5n + 9

                                                            Width =  5n - 3.5

____________________________________________________

-> 2(Length) + 2(Width)

-> 2(3.5n+9) + 2(5n-3.5)

*distribute*

-> (7n+18) + (10n-7)

*distribute*

->7n+18+10n-7

->17n-11

which expressions represents a 20% discount off the price of an item that originally cost D dollars ​
Charra [1.4K]

Answer:

D - (D/5)

Step-by-step explanation:

Let's imagine that D equals 100 dollars -

Well, we know that to get 20% of an amount, we need to divide the amount by five. So let's do that -

100 / 5 = 20

We now know that 20% of 100 dollars is equal to 20 dollars. We have now finished the first part. On to the second part.

We now need to take away 20% of 100 dollars off of 100 dollars - this is the price of the item after the discount.

100 - 20 = 80 dollars.

We now fit in D instead of 100 dollars -

D - (D/5)

Activity paper to answer
PIT_PIT [208]

Answer:

1.

a) 5cm

b) 16cm

c) 25cm

d) 124cm

2.

a) 4m

b) 6m

c) 10m

d) 26m

3.

a) 2km

b) 4km

c) 11km

d) 28km

Step-by-step explanation:

When you have a number and it tells you to round it to the nearest cm (m, km etc.), it means you just have to make it a whole number (integer) instead of a decimal by rounding it up or down.

To tell whether you round up or down, you look at the number after the decimal place and if it is under 5, you round down but if it is 5-9 you round up.

For example,

If we had 20.3 (not one of the questions) you would round it down to 20 because the 3 after the decimal place is smaller than 5.

However, if we had 24.7 you would have to round it up because the 7 is from 5-9.

Hope this helps :)
