A = L * W
(9/10) = (3/2) * W
Divide both sides (3/2)
(9/10) / (3/2) = W
(9/10) * (2/3) = W
18/30 = W
6/10 = W
W = 3/5 mile
X = -10
work:
1. <span>4.5(8-x) + 36 = 102 - 2.5(3x+24)
2.</span>4.5(8-x) * 10 + 36 *10 = 102 * 10 - 2.5(3x + 24) * 10
3. 45(8 - x) + 360 = 1020 - 25(3x + 24)
4. -45x + 720 = -75x + 420
5. -45x + 720 - 720 = -75x + 420 - 720
6. -45x = -75x - 300
7. -45x + 75x = -75x - 300 + 75x
8. 30x = -300
9. 30x/30= -300/30
SIMPLIFY = x = -10
Answer:
y = -1/2x - 4
Step-by-step explanation:
6y = -3x - 24 ---> y = -3/6x - 4 ---> y = -1/2x - 4
y=4x+8x -> 4+8=12x
12x=y -> divide by 12 both sides
x=y/12
