Answer:
x = 6
Step-by-step explanation:
Given that PQ = 3x + 14, QR = 7x - 10, and Q is the midpoint of PR, it means Q is equidistant from both endpoints of P and Q. In order words, the distance from P to Q is the same as the distance from Q to R.
Therefore, PQ = QR. Which is:
Solve for x. Collect like terms
Divide both sides by -4x
Answer:
1st equation: 3(12) - 12 = 24
2nd equation: 36 - 12 = 24
-9.4=>1.7x+4.2
-1.7x=>13.6
x<=8
Answer:
25
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
set up proportion based on corresponding sides of similar triangles:
15 / 10 = 15 + x / 12
cross-multiply:
10(15 + x) = 15(12)
150 + 10x = 180
10x = 30
x = 3
