You said 2x - 9 < 7
Add 9 to each side: 2x < 16
Divide each side by 2 : x < 8 .
56 students represents 100 % and
X boys represent 34%,
so x= 56•34/100= 19.04 so approximately 19 boys
56-19= 37 girls signed up.
Now 37 girls represent 100% and 31 girls represent x % ,
So x= 31•100/37= 83.78% about 84% of the girls attended
Answer:
65950
Step-by-step explanation:
10,000 + 70 x 800 - 50
10,000 + 56,000 - 50
66,000 - 50
65950
Answer:
x < -8
Step-by-step explanation:
<h3>
Answer: A) zero velocity</h3>
Explanation:
Recall that the slope is equal to the rise/run.
Rise = change in y = change in distance
Run = change in x = change in time
If we have a horizontal line, then there is no change in y. The rise would be 0 here. The run can be anything you want. Let's just call it x
Slope = rise/run = 0/x = 0
Therefore, all horizontal lines have a slope of 0.
The slope of a distance time graph represents the velocity because
velocity = (change in distance)/(change in time) = rise/run = slope
for example, a velocity of 10 meters per second represents a change of 10 meters over 1 second. The rise here woud be 10 meters and the run would be 1 second.
