X = 8.
We know this since the line in question is vertical, so we automatically know it will be x (vertical lines can only pass through the x axis, because the y axis is already vertical).
Vertical lines will pass through only 1 x-coordinate, but they pass every point on the y-axis, since they infinitely go up and down (which, we already said, is the y-axis).
Answer:
Average speed v = 83.8 km/h
Step-by-step explanation:
Given;
Distance travelled = 95 km
Time taken t = 12.23 - 11.15 = 1 hour 8 minutes
t = 1 + 8/60 hours = 1.133 hours.
Average speed v = distance travelled/time taken
substituting the values;
v = 95 km ÷ 1.133 hours
Average speed v = 83.8 km/h
I’m pretty sure it’s x=40
Answer:the number of advance tickets sold is 35
the number of same day tickets sold is 40
Step-by-step explanation:
Let x represent the number of advance tickets sold.
Let y represent the number of same day tickets sold.
For one performance, there were 75 tickets sold in all. This means that
x + y = 75
Advance tickets cost $20 and same-day tickets cost $25. The total amount paid for them was $1700 both tickets. This means that
20x + 25y = 1700 - - - - - - - - - - - 1
Substituting x = 75 - y into equation 1, it becomes
20(75 - y) + 25y = 1700
1500 - 20y + 25y = 1700
- 20y + 25y = 1700 - 1500
5y = 200
y = 200/5 = 40
substituting y = 40 into x = 75 - y, it becomes
x = 75 - 40
x = 35
Answer:
Water = 1/5 of the volume of the syrup
Step-by-.step explanation:
Suppose we had 1000 cm^3 of syrup and the new volume after adding water is x cm^3. Now the amount of sugar stays the same so we have the equation 35 * 1000 = 25 * x
x = (30 * 1000) / 25 = 30,000 / 25
= 1200 cm^3
So we need to add 200 cm^2 of water .
In general terms, we need to add water which equals 1/5 of the volume of the syrup,
