tigry1 [53]

Answer:

Pls help me to answer this​
Flauer [41]

Answers:

T-shirt = $25

Shorts = $15

Books = $50

Shoes = $30

Cell phones = $750

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

Explanation:

Taking 10% of a number is simply moving the decimal point over one spot to the left.

For example, the selling price of a t-shirt is $250.00 and taking 10% of this gets us to $25.00

As another example, 10% of 150.0 is 15.0

If a whole number ends with a 0, then taking 10% of the number means we chop that zero off.

It’s possible to build a triangle with side lengths of 5,5, and 10
nikitadnepr [17]
No.  The two lengths 5 and 5 add up to 10; you'd have two sides of length 5 each placed end to end, equaling 10.  That'd be represented by segments on a straight line, not a triangle.

Hope you've drawn a picture, so as to understand this better.  ;)
