Answer:
g = 1/2
Step-by-step explanation:
Step 1: Add 0.5g to both sides
9 + 4g = 11
Step 2: Subtract 9 from both sides
4g = 2
Step 3: Divide by 4 on both sides
g = 2/4
Step 4: Simplify
g = 1/2
Answer:
A. 360
Step-by-step explanation:
360 total students / 40% population of girls = 144 are girls
4x + 6 < -6
subtract 6 from each side
4x < -12
divide by 4
x < -3
- 2/5 x-9 < 9/10
multiply each side by 10 to get rid of the fractions
10*(- 2/5 x-9) < 10*9/10
distribute
-4x -90 <9
add 90 to each side
-4x < 99
divide by -4 (which flips the inequality)
x> -99/4
x> -24 3/4
Answer:
A to B = 2000 m/s
C to D = 30,000m/s
Step-by-step explanation:
A to B is 10secs and the distance is 200m so you multiply them and you get 2000m/s
C to D is 60secs and the distance is 500m so you multiply and you get 30,000m/s
