Answer:
x = 4
Step-by-step explanation:
1.5(x + 4) – 3 = 4.5(x – 2)
Distributive property
1.5x + 6 - 3 = 4.5x - 9
1.5x + 3 = 4.5x - 9
1.5x - 4.5x = -9 -3
-3x = -12
x = 4
Total distance =(250+90)n
=300 m
time =12 sec
speed time/distance
speed = 12/300
speed =25 sec
Answer:
1 whole
Step-by-step explanation:
12 1/4 can be rewritten as 12.25
Then move the decimal place two places to the left to divide by 100 (percent means per 100),
Final answer: 0.1225
