Answer:
x=4-3/x
Step-by-step explanation:
x^2-4x+3=0
x^2-4x=-3
x^2=4x-3
x=4-3/x
Answer:
renting a movie for 2 dollars a day
Step-by-step explanation:
the y does not repeat
Step-by-step explanation:
For finding range we will arrange it from least to greatest
0.50 1 1 1 1 2.50 2.50 3 4
So range = 4 - 0.50 = 3.50
2.4,3, 7 1/3, 221/30,7.36 is order from least to greatest
For question 4, 
Question 5. Option a and question 6. Option j
Step-by-step explanation:
Step 1:
The three basic formula needed to solve these questions are:

Step 2:
Using the above formula, we solve the following values









Step 3:
For question 5, The triangle's angle = 23°, opposite side = BC inches and hypotenuse = 4 inches.

SO BC is 1.5628 inches, rounding this off to the nearest tenth, we get BC = 1.6 inches which is option a.
Step 4:
For question 6, The triangle's angle = 50°, opposite side = QR m the adjacent side = 8.1 m.

SO QR is 9.65277 meters, rounding this off to the nearest tenth, we get QR = 9.7 inches which is option j.
