Option 1 : 20 + 1.25d
option 2 : 2.50d
when will they be equal......so set them equal to each other
20 + 1.25d = 2.50d
20 = 2.50d - 1.25d
20 = 1.25d
20 / 1.25 = d
16 = d.....so they will be equal at 16 dvd rentals
Answer:
TQ = 10
Step-by-step explanation:
The diagonal divides the square into 2 right triangles with the diagonal being the hypotenuse.
Using Pythagoras' identity in triangle TPQ
TQ² = PQ² + PT²
TQ² = 10² + 10² = 100 + 100 = 200 ( take square root of both sides )
TQ = 
= 
= 
× = 10
Answer:
A
Step-by-step explanation: 5x10 =50+10 =60 the number of students
Y + 8 = 4(x - 5)
distribute the 4 to both x and -5
4(x) = 4x
4(-5) = -20
y + 8 = 4x - 20
isolate the y, subtract 8 from both sides
y + 8 (-8) = 4x - 20 (-8)
y = 4x - 28
plug in the x given, if the y matches the answer given, it is the correct answer.
-8 = 4(5) - 28
-8 = 20 - 28
-8 = -8 (True)
D) (5,-8) should be your answer
hope this helps
