The equation is 2.5x + 2y - 2 = 0.
<h2>Linear system</h2>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
He bought 2.5 pounds of apples that are x dollars a pound.
And 2 bags of lettuce for y dollars each.
The total cost is $2.
<h3>To find </h3>
The equation of this.
<h3>How to find the equation?</h3>
He bought 2.5 pounds of apples that are x dollars a pound.
Then the expression is 2.5x
And 2 bags of lettuce for y dollars each.
Then the expression is 2y
The total cost is $2.
Then the expression will be
2.5x + 2y = 2
2.5x + 2y - 2 = 0
Thus the equation is 2.5x + 2y - 2 = 0.

Answer:
4) 0.001
Step-by-step explanation:
The amount (a) present in h hours is ...
a(h) = (initial value)×(1/2)^(h/(half-life))
6 days is 6×24 hours, so the amount remaining is ...
a(6×24) = 50×(1/2)^(6×24/9) = 50/2^16 ≈ 0.001 . . . . milligrams
