Answer:
the solution of the system is:
x = 1 and y = 2.
Step-by-step explanation:
I suppose that we want to solve the equation:
-6*x + 6*y = 6
6*x + 3*y = 12
To solve this, we first need to isolate one of the variables in one of the equations.
Let's isolate y in the first equation:
6*y = 6 + 6*x
y = (6 + 6*x)/6
y = 6/6 + (6*x)/6
y = 1 + x
Now we can replace this in the other equation:
6*x + 3*(1 + x) = 12
6*x + 3 + 3*x = 12
9*x + 3 = 12
9*x = 12 - 3 = 9
x = 9/9 = 1
Now that we know that x = 1, we can replace this in the equation "y = 1 + x" to find the value of y.
y = 1 + (1) = 2
Then the solution of the system is:
x = 1 and y = 2.
Answer: I think the answer is B
Step-By-Step Explination:
First you find out what x is by doing 42 multiplying it by 0.1 witch equals 4.2 gallons per mile
Next you figure out what y is by doing 4.2y (witch is 4.2 times y)
The answer is (3p-5pt)/12
remove parenthesis but the terms are connected.
Answer:
the answer is 3
Step-by-step explanation:
in the number 66 there are "2" circles in them and so the answer we get 2
in the number 99 there are "2" circles and so the answer there is 2
in the number 888 there are "6" circles so the answer is 6
in the number 00 there are "2" circles that's the answer
in the number 7777 there are no circles so the answer is 0
we keep on going like that......
in the number 2876 there are 3 circles 2 in the number 8 and 1 in the number 6
hope this helped :D
