Answer:
(1, 6 )
Step-by-step explanation:
5x + 2y = 17 → (1)
4x + y = 10 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate the y- term
- 8x - 2y = - 20 → (3)
Add (1) and (3) term by term to eliminate y
- 3x + 0 = - 3
- 3x = - 3 ( divide both sides by - 3 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for x
Substituting into (1)
5(1) + 2y = 17
5 + 2y = 17 ( subtract 5 from both sides )
2y = 12 ( divide both sides by 2 )
y = 6
solution is (1, 6 )
Option C: x = 5.5 is the value of x
Explanation:
Given that CD, AE, an BF are the medians of the triangle ABC
Also, given that
and 
We need to determine the value of x.
Since, we know that the centroid divides the median in the ratio 2 : 1
Hence, we have,

Substituting the values, we get,

Simplifying, we get,

Subtracting both sides of the equation by 2x, we have,

Adding both sides of the equation by 5, we have,

Dividing both sides of the equation by 2, we get,

Therefore, the value of x is 5.5
Hence, Option C is the correct answer.
Answer:
multiply both sides by 3x + 7
Step-by-step explanation:
this will eliminate the fraction in the equation and therefore make it easier to isolate x
