Answer:
x = 1, y = 2
Step-by-step explanation:
In the elimination method to solve a system of linear equations, one of the two equations is added/subtracted to the other, in order to eliminate one variable from the equation.
In this problem, we have the following two equations:
To solve the system, first we multiply by 2 both sides of the second equation, and we get:
So now the system is
Now we add the two equations, and we get:
So, we get
Now we can substitute this value of y into the eq.(2), and we get:
Answer:
the time means how long it takes to get to that distance below it

Answer:
(p - 8)(p - 9)
Step-by-step explanation:
We need 2 numbers whose product is + 72 and whose sum = -17.
They are -8 and -9
Answer: Let the Number of hours Enzo sleeps on average per day while School is in session be Y
Y = SS/115% = SS/1.15
Step-by-step explanation:
Given in the question:
- While on vacation, Enzo sleeps 115% as much as he sleeps when school is in session.
- Enzo sleeps SS hours per day during vacation
Mathematically, SS = 115% of Y
SS = 115% × Y
115% × Y = SS
Y = SS/115%
But 115% = 115/100 = 1.15
Therefore,
Y = SS/1.15
Solved!
