Answer:
- 2 < x < 2
Step-by-step explanation:
Given
- 3 < 2x + 1 < 5 ( subtract 1 from each interval )
- 4 < 2x < 4 ( divide each interval by 2 )
- 2 < x < 2
Answer:
-4y = -x + 32
y = x/4 - 8
or y = (1/4)x - 8
Step-by-step explanation:
443.75 - (25 x 7.25) =25x
443.75 - 181.25 = 25x
262.5 = 25x
x = 10.5
$10.50
First, you add 1 to both sides. Then square both sides to get rid of the square root. After that you just solve it like a normal equation when you are left with 4x-2=9.
