5. When looking at a map, a student realizes that Birmingham is nearly due west of Atlanta, and Nashville is nearly due north of
leonid [27]

Answer: 250 mi

Step-by-step explanation:

Here we can think in a triangle rectangle:

The distance from Birmingham to Atlanta is roughly 150 mi, and this is one of the cathetus.

And the distance from Birmingham to Nashville is roughly 200 mi, this is the other cathetus of the triangle.

Now, the distance from Atlanta to Nashville will be the hypotenuse of this triangle rectangle.

Now we can apply the Pythagorean's theorem:

A^2 + B^2 = H^2

Where A and B are the cathetus, and H is the hypotenuse:

Then:

H = √(A^2 + B^2)

H = √(150^2 + 200^2) mi = √(62,500) mi = 250 mi

Then the estimated distance from Atlanta to Nashville is 250 mi

Edmund purchased a computer for $1,800 on a payment plan (month zero). Three months after he purchased the computer, his balance
trapecia [35]

Answer:

Well I can't make a table but I can explain the answer.

Step-by-step explanation:

So you have $1,800 on a payment plan.  In three months, the balance is 1,350.  So 1,800-1,350=450.  This means he paid $450 in three months.  450/3 is 150.  He pays $150 a month.  Then 2 months later, (5 months after purchase) he has balance is $1,050.  1,350-1,050=300.  300/2=150.  Further evidence of the fact that he pays 150 dollars a month.  This means that the 6th month, he will have $900 dollars left on the payment.  7th month... $850, 8th month... $600, 9th month... $450, 10th month... 300 dollars, 11th month... 150, and 12 month he will have paid off all of his computer.  Hope it helps, sorry it is so long.  Have a great day!  :D

5x = 65

x = 65 / 5

x = 13

TY = TU ( Reason : from given )

3y + 5 = 50

3y = 50 - 5
