Answer:
10 9/20
Step-by-step explanation:
<em>Hey there!</em>
If Hillsboro to Campbell is 16 2/20 and Hillsboro to Oxford is 5 13/20,
we’ll do
16 2/20 - 5 13/20
Imrpoper form
322/20 - 113/20
322 - 113
209/20
10 9/20 miles from Oxford to Campbell.

Answer:
Equation: y = 2x + 7
Step-by-step explanation:
If the line is parallel to the line resembling the equation y = 2x - 4, it would mean that the line would have a similar slope, leading to part of the equation:
y = 2x
Now substitute the x-coordinate -2 and y-coordinate 3 into the equation * (derived from (-2, 3) ):
3 = 2(-2)
Now simplify either side:
3 = -4
For 3 to equal -4, you would have to add 7:
3 = -4 + 7 = 3
This means the final equation is:
y = 2x + 7
(Sorry if this isn't the way you expected to solve the question)
Hey there!
To solve a system of equation by graphing, first make sure both your equations are solved for y so that you can graph it (make sure it is in a form like: y=mx+b or y=ax^2+bx+c, etc).
Then, graph the equations on the graph, and the point where all the lines intersect would be your answer which should look like: (x,y)
However, if you have linear equations and the lines are parallel to each other, then there is no solution. If the lines graph to be the same line, then your answer would be all real solutions.
Let the no. of $10 bills be x, the no. of $5 bills be 2x, and the no. of $20 bills be y.
<span>A cashier collects 124 bills => x + 2x + y = 124 => 3x +y =124
</span>totaling $920 dollars => ($10)(x) + ($5)(2x) + ($20)(y) = $920 => 20x + 20y = 920
Now you got 2 equations :
3x +y =124 &
20x + 20y = 920
3x +y =124 => y=124-3x
Then Sub y=124-3x into 20x + 20y = 920,
ie. 20x + 20(124-3x) = 920
20x + 2480 - 60x = 920
2480 - 40x = 920
2480 - 920 = 40x
1560 = 40x
x = 39
