**Answer:**

Below.

**Step-by-step explanation:**

When dealing with discounts, to find the amount that will be subtracted from the price, you will need to move the decimal two places (I think, don't quote me on that) to the right and then multiply the cost of the item with the discount. Seeing as the discount is 10% off, we have to multiply the cost of the item times the discount. (If the price of the rs550 is $100, we would times 100 by 0.10 to get $90.00 for the price of the item.)

Examples:

10% off = 0.10

60% off = 0.60

26% off = 0.26

etc.

**Answer: Yes it is**

**Step-by-step explanation:**

**You have to take 2 times 5/2 witch is the same is 2.5 **

So 2.5 times 2

3 times 2.5

6 times 2.5 and that's how you get the answer

**Answer:**

A

**Step-by-step explanation:**

Slope is the first y - the second y divided by the first x- the second x. Therefore we take -8-4= -12 and -7-0= -7. Using the formula, we get -12/-7. The negatives cancel out and we get 12/7 which is A.

**Answer:**

4

**Step-by-step explanation:**

multiply 3 by 4 to get 12 and add 12 to 2 and you get 14

**Answer:**

17

**Step-by-step explanation:**

Seeing that traingle ABC is = to triangle DEF.

It means that the angles are equal too.

So you would equate them to each other.

Hence 5X+2=87

5X=87-2

5X=85 (divide by 5)

X=17

Hope that helps :)
