This can be solved using the
angle bisector theorem. Note that line segment AD is the angle bisector of triangle DAB from angle DAB. Therefore, we know that the ratios
and
are equal. Solving, we get
. Cross multiplying, we get
, and solving this equation we get
.
10.2 is your answer.
Answer:
(7, -27)
Step-by-step explanation:
Use the midpoint formula.
M = ( x₂ + x₁ , y₂ + y₁) / 2
(5, -11) = (x₂ + 3 , y₂ + 5) / 2 Substitute the midpoint and point U.
(10 , -22) = (x₂ + 3 , y₂ + 5) Multiply by 2 on both sides
x₂ + 3 = 10 y₂ + 5 = -22 Split for each point and solve.
x₂ = 10 - 3 y₂ = -22 - 5
x₂ = 7 y₂ = -27
Point V is (7, -27).

24*0.05=1.20
Answer:
Step-by-step explanation:
2. 2(3x+4)=10
6x+8=10
6x+8-8=10-8
6x=2
x= 1/3
3. 2x + 7 = 5x + 16
7 + 2x = 5x + 16
7 + 2x = 16 + 5x
7 + 2x + -5x = 16 + 5x + -5x
7 + -3x = 16 + 5x + -5x
7 + -3x = 16 + 0
7 + -3x = 16
7 + -7 + -3x = 16 + -7
0 + -3x = 16 + -7
-3x = 16 + -7
-3x = 9
x = -3
4. x/3-8=-2
x/3=6
x=18
5. 3x-6=-12
3x-6+6=-12+6
3x=-6
x=-2
sorry but i cannot solve 1 or 6 because i am quite stupid
