Let the number of equations be x and the number of vocabulary questions be y.
x + y = 26 (total num of questions)So, y = 26 - x (eliminate one variable to solve for one first)2x + 5y = 100 (total points)2x + 5 (26 - x) = 100 (substituting 26 - x in place of y)
2x + 130 - 5x = 100 (distributing the 5)-3x = -30x = 10
Since there are 10 equation questions, there must be 16 vocabulary questions to satisfy the total number of questions in the test...
Answer:
3
Step-by-step explanation:
3x=x+6
3x-x=6
2x=6
divide both sides by 2
x=3
The length of the sides of the triangle are; RS =√5, ST= √17 and RT=√18, their slopes in the same order are; (1/2), -4 and -1.
<h3>What is the slope about?</h3>
The length of each side can be solve for by the following ways;
Side RS = √((4-2)² + (4-3)²) = √5
Side ST = √((5-4)² + (0-4)²) = √17
Side TR = √((5-2)² + (0-3)²) = √18
The slopes can be examined as;
Slope RS = (4-3)/(4-2) = 1/2
Slope ST = (0-4)/(5-4) = -4
Slope TR = (0-3)/(5-2) = -1.
Therefore, one can say that triangle RST into one of three types of triangles:
- Scalene
- Isosceles
- Equilateral
