Answer:
x=y-p+q
Step-by-step explanation:
y=x+p-q
x=y-p+q
I used the area of a parallelogram formula which is base into height and equated them
13*h=18*12 solving this, you get h=16.61 and so on
A= 3R
R = A/3
24= A + R
24= 3R + R
24 = 4R
6= R
A= 18
Roman = 6
Alex = 18
6+18 = 24
Answer:
They need five weeks to make all their travels.
Step-by-step explanation:
Given that Cesar and Jocelyn are planning their trips to three countries next year.
One trip will be one week long, another two days, and the other two weeks.
In conclusion, they need five weeks to make this travel.
Let us suppose a system of two equations with two unknowns.
Suppose further that the system of equations is linearly independent.
When the system of equations has a variable that has exactly the same coefficient in both equations, then the most effective method to solve the system of equations is subtracting.
This is because we eliminate one of the variables and reduce the system to an equation with one unknown.
Answer:
a system of equations in which subtraction would be the most efficient way of solving the system is:
A system of equations in which one of the variables has exactly the same coefficient in both equations.
