First write the inequality: 15

4.75x +3.50
Then to solve, first subtract 3.50 from both sides to get:
11.50

4.75x
Then divide by 4.75 to get 2.42, and since you can't buy .42 of a bag of fruit, you round down. So your final answer would be 2 bags of fruit.
Answer:

Step-by-step explanation:
Given
tan a =
= 
We require the hypotenuse h
Using Pythagoras' identity
h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )
h =
= 41 , thus
sin a =
= 
cos a =
= 
7y - 3x = -5
-3x = -7y - 5
x = 7/3y + 5/3
