Answer:
The required expression is 
Step-by-step explanation:
Consider the provided information.
She makes a base pay of $100 each day and is also paid a commission for each sale she makes.
One day, Lily sold 4 computers and was paid a total of $110.
Let z is the commission for each sale.
Therefore, 4z is the total commission after selling 4 computers.



Therefore, she is earning $2.5 for each computer sold.
Hence, the required expression is:

Where x is the number of computer she sells.
Answer:
Step-by-step explanation:
This is the equation of a circle with center at (-4, 6) and radius 4√3.
Answer:
a)
x = (158-112) / 1x
or 158-112 / x
b) 112+ 23 /158-23 = x
or if you want x to be the same value as the first part then you could write
112+x / 158-x = 135/135
or revise as an equality
23 ≤ 112 < 158
112 + 23 = 158
112 + x = 158
Step-by-step explanation:
Tailwind speed
x = 158-112 / 2
x = 46/2
x = 23 knots
Speed
x = 112 + 23 / 158-23
x = 135 / 135 m/h = same speed as stated in question.
