Answer: $4.50
Step-by-step explanation:
125=21.50+23x
This is the equation to find this situation since 125 was given and it equals the left over and the spent money.

103.5=23x
Very cool! Divide both sides by 23 to get 4.5=x
Answer:
i need 5 points im sorry mate
Step-by-step explanation:
For a line in the form:

In this case, for the line 2x + 10y = 20 with a=2 and b=10 the slope is:

Now, two lines are perpendiculars if the slopes satisfy the following equation:

So, for the line we want the slope is:

Finally, the line pass througth the point (2, 3) with slope m=5, so the equation is:

The equation of the line is y = 5x - 7
