Just simplify the given equation
y = 7.2 + 4(x-2)
y = 7.2 + 4x - 8
y = 4x - 0.8
Now they want to know the answer if X = 2
y = 4(2) - 0.8
y = 8 - 0.8
y = 7.2
Answer:
Nine
Step-by-step explanation:
3 dollars for children tickets : x
5 dollars for adult tickets: y
Equation is:
3x+5y=57
Where 57 is the total amount spent
x+y=15
where 15 is the total number of tickets bought
3x+5y=57
5(x+y)=5(15)
___________________
3x+5y=57
5x+5y=75
minus the equations top to bottom=
-2x= -18
x= -18/(-2)
x=9
He bought a total of 9 children tickets
The length of the unknown side is 16 meters
<h3>What is a right triangle?</h3>
A right triangle is a triangle that has one of its angles to be 90 degrees
The length of the unknown side is calculated using the following Pythagoras theorem.
Evaluate the exponents
Collect like terms
Evaluate the like terms
Take the square root of both sides
Hence, the length of the unknown side is 16 meters
