Answer:
angles in linear pair are 90° hope it helps u ♥♥♥♥♥♥♥
If ice tea is lets say y (ice tea = y) and water is x (water = x) then the answer is
1.25x + 1.49y = 100
the error is that she forgot the second variable(y).
The approximate solution to the given system of equations, considering the graph, is given as follows:
D.

<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
On a graph, the solution of a system of equations is given by the intersection between the curves. In this graph, the intersection of the two curves happen close to x = -3.25, y = 2.5, hence the solution is approximated by:
D.
