The regular price of an item at a store is p dollars. The item is on sale for 20% off the regular price. Some of the expressions
ruslelena [56]

Answer:

Expression B: 0.8p

Expression D: p - 0.2p

Step-by-step explanation:

The regular price of an item at a store is p dollars. The item is on sale for 20% off the regular price. Some of the expressions shown below represent the sale price, in dollars, of the item.

Expression A: 0.2p

Expression B: 0.8p

Expression C:1 - 0.2p

Expression D: p - 0.2p

Expression E: p - 0.8p

Which two expressions each represent the sale price of the item?

Regular price of the item = $p

Sale price = 20% off regular price

Sale price = $p - 20% of p

= p - 20/100 * p

= p - 0.2 * p

= p - 0.2p

= p(1 - 0.2)

= p(0.8)

= 0.8p

The sale price is represented by the following expressions

Expression B: 0.8p

Expression D: p - 0.2p

Answer:

X=35

Step-by-step explanation:

X=35 because a straight line is 180 degrees. Take away 60 degrees and you're left with 3x + 15 = 120. Simplify to 3x=105, and then divide 3x by 3. Do the same to the other side. X will now equal 35. Hope this helps :)
