Answer:
202 tickets for adults were sold and 70 tickets for children are sold.
Step-by-step explanation:
Solve this question using simultaneous linear equation.
•Let the number of tickets sold for adults be a
•Let the number of tickets sold for children be b
The question stated that 272 tickets were sold altogether. So:
Now, make sure that only one of the unknown values remain on the left hand side. For example:
I will refer to the above equation as equation 1.
Now, the question also stated that the tickets sold $1694. This means that:
I will refer to this equation as equation 2.
Now, substitute equation 1 into equation 2 by replacing the a in equation 2 with the values on the right hand side in equation 1. For example:
Then just solve the equation by finding the value of b.
Lastly, find the value of a. Just take the value of b and then substitute into equation 1.
Answer:
y= 5x +12
Step-by-step explanation:
y=mx+b is slope intercept form
m = slope
b = y intercept
Answer:
22 meters.
Step-by-step explanation:
There is a pond between two points A and B.
To avoid the pond, one must walk to the south from point A to point C (say) by 34 meters and then to the east from point C to point B by 41 meters.
Now, it is clear that Δ ABC is a right triangle with AB as the hypotenuse that is the minimum distance from A to B through the pond.
The two legs of the right triangle are AC and CB.
Applying Pythagoras Theorem, AB² = AC² + CB² = 34² + 41² = 2837
⇒ AB = 53 meters (Rounded to the nearest meter)
Therefore, (34 + 41) - 53 = 22 meters will be saved if it were possible to walk through the pond. (Answer)

Step-by-step explanation:
Answer:
7230 gallons
Explanation:
The total water pumped out is equal to 210 multiplied by 3 which equals to 630 gallons.
This gives the volume of the tank 3 days ago as 630 + 6600 = 7230 gallons
