Answer:
$95 FOR A DRESS
Step-by-step explanation:
Let's rearrange the given:
She bought a blouse and skirt for two, a blouse and a dress for two, and a blouse for two.
A blouse and a skirt cost $107
A blouse and a dress cost $134
blouse cost x dollars
The equation:
2($107) + 2($134) + 2x = $560
SOLUTION:
$214 + $268 + 2x = $560
2x = $560 - $214 - $268
2x = $78
x = $39 for a single blouse
FIND THE COST OF DRESS:
A blouse and a dress cost $134 - $39 for a single blouse
$134 - $39 = $95
$95 IS THE COST OF DRESS
Answer:
hello : coordinate pair is: (5 ; 1)
Step-by-step explanation:
you have this system :
5x - 3y=22 ......(1)
-4x + y= -19.....(2)
by (2) : y = 4x -19
put y in (1) : 5x - 3 (4x -19) =22
5x -12x +57 = 22
- 7x = -35
x = 5
but : y = 4x -19 so : y = 4(5) -19 = 1
coordinate pair is: (5 ; 1)
