Step 1. Multiply first equation with -3 and the second one with 2. You'll get:
Step 2. Add both equations together. You'll get:
, which gives x = -2
Step 3. Replace x = -2 in the first equation and calculate y.
The solution is: x=-2, y=5
Answer:
8.5 for each student ticket
Step-by-step explanation:
Simply divide the total cost 42.5 by the amount of students 5 to get your answer.
42.5 / 5 = 8.5
Subtract 1.75 from 5.00
5.00-1.75= 3.25

-1
Step-by-step explanation:
Answer:
The slope formula can be used to prove that a triangle has
A. Congruent Sides
<u>B. A right angle
</u>
C. Parallel sides
D.Congruent angles
Step-by-step explanation:
The formula for finding the slope of a line on a coordinate plane is (y2 - y1) / (x2 - x1), where (x2, y2) and (x1, y1) represent two distinct points on the line. This is also known as "change in y over change in x" or "rise over run."
