“Trish has a jug of contaminated water that she knows is only 75% clean. She also knows that the water will be safe to drink if she can mix it with 100% clean water so that it is 97% clean. How much
clean water (100% clean) would Trish need to mix with the contaminated water in order to get 1 gallon
of drinkable water?"
A student used the following system of equations to model the situation given above. Which of the
statements is true about the system of equations the student used?
75x + 100y = 97(1)
Lx-y=1
A. The system of equations the student used is correct.
B. The top equation in the system is incorrect.
C. The bottom equation in the system is incorrect.
D. Both equations in the system are incorrect.

he will have 300 because he is really broke and 300 is in his imangine

step-by-step explanation: he ehe heh step by the thy

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
