Answer: The monthly payment assuming that each month he paid the same amount is = 362.5 $
Step-by-step explanation:
Given data,
Johnny bought a used car for $7,500
He had $4600 and borrowed the rest from his parents.
Johnny 8 months to pay back the money he borrowed
So, we can write ,
Let us assume, x1 = $7,500 and x2 = $4600
Based on the given conditions,
we use formula is :
x = ( x1 - x2 ) / pay back months
x = ( 7,500 - 4,600 ) / 8
we can subtract the values,
we can write,
x = 2900/8
x = 725/2
x = 362.5 $
Therefore,
The monthly payment assuming that each month he paid the same amount is = 362.5 $.

Answer:
<em>The ladder needs to be placed at 5 m from the wall.</em>
Step-by-step explanation:
<u>Pythagoras's Theorem</u>
Being a and b the legs of a right triangle and c its hypotenuse, then
The image shows a ladder of length c=13 m as the hypotenuse of the right triangle formed by the height, the ladder, and the ground.
We are given the height up the wall as a=12 m.
We calculate the distance b solving it from the equation above:
Substituting:
Operating:
Taking the square root:
b = 5 m
The ladder needs to be placed at 5 m from the wall.
