Answer:
5
Step-by-step explanation:
10 - 5 = 5 the range is the difference from the highest value to the lowest value
Just do what you said (subsitute) and solve
x=number of classes
7.5x=5.5x+10
subtract 5.5x from both sides
2x=10
divide 2
x=5
5 classes
to find how much it costs, subsitute 5 for x in any equation
y=7.5(5)
y=37.5
total cost is $37.5 per month
<span>a=7b+8c+9d-10
8c = a - 7b - 9d + 10
c = (</span>a - 7b - 9d + 10) / 8
Answer:
No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
Step-by-step explanation:
Let larger number be X and smaller one be Y.
The two equations are :-
X = 2Y + 3
X = 2Y + 1
As you can tell, the slopes are the same and the y-intercepts are different. So, they will not intersect. Therefore, no solutions exist for this situation.
