Vsevolod [243]

Answer:

the answer is

A. X=2, y=6

Step-by-step explanation:

use substitution

y= 6 so,

y-3 = 6-3 which is 3

and y-1 = 6-1 which is 5

now for x

x=2

x+3= 2+3 which is 5

2x-1= 2(2)-1

2 times 2 is 4

4-1 = 3

The clothing store marked down all their shirts by 30%. If a shirt originally cost $24, what is the sale price of the shirt?
Alona [7]

Answer:

$16.80

Step-by-step explanation:

Since the shirts are marked down by 30%, you need to multiply the cost of the shirt by the percentage.

$24 × 0.3 = $7.20

Next, subtract the discount from the original price to find the discounted price.

$24 - $7.20 = $16.80
