Since, the fraction cannot be reduced, that is the answer.
Answer:
One cup of coffee is $3.25
Step-by-step explanation:
Create a system of equations where c is the cost of a cup of coffee and d is the cost of a donut
2c + 4d = 10.5
c + 5d = 8.25
Solve by elimination by multiplying the top equation by -5 and the bottom equation by 4
-10c - 20d = -52.5
4c + 20d = 33
Add them together and solve for c
-6c = -19.5
c = 3.25
So, a cup of coffee is $3.25
First of all, we know that a line is 180°. This means if we add the angles of 61°, 57°, and angle y, we should get 180<span>°.

Simplify:

Subtract 118° to both sides:

We also know that all three angles of a triangle add up to 180<span>°. So we have:

Simplify:

Subtract 129° to both sides:

All you need to do is subtract.
1-5 is -4. 1-3 is -2 thus (-4,-2)
4-5=-1. 2-3=-1 thus (-1,-1) at this point there is only one option left
B Is the answer
