Answer:
B. 
Step-by-step explanation:
we know that
If a ordered pair is a solution of a linear equation. then the ordered pair must satisfy the linear equation
In this problem we have

<u>verify each case</u>
case A) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is not true
therefore
The ordered pair case A) is not a solution
case B) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is true
therefore
The ordered pair case B) is a solution
case C) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is not true
therefore
The ordered pair case C) is not a solution
case D) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is not true
therefore
The ordered pair case D) is not a solution
Answer:
16 dimes and 1 nickel
23 nickel and 1 dime
These are just two you have so many options, just mess with it
3/6 = 6/x+3
3x + 9 = 36
3x = 27
x = 9
The answer is x=-6.33333 (-19/3)
First, add like terms (12+7), which would equal to 19.
Then isolate the variable by subtracting 19 and adding it to the other side of the equal sign.
Now with this new equation of 3x=-19, isolate again by dividing 3 from x and do the same thing to the other side (-19/3).
The answer should be -6.33 repeating, but in algebra you would give a more simplified answer. This would be -19/3
Answer:
3/70
Step-by-step explanation:
change 1/10 and 1/7 so the denominator (bottom number) is the same. 1/10= 7/70 and 1/7= 10/70 so you need 3/70 to make the two numbers equal.
