Answer:
15/2 or 7.5
Step-by-step explanation:
![5/6 (x + 1/2 + 4)](https://tex.z-dn.net/?f=5%2F6%20%28x%20%2B%201%2F2%20%2B%204%29)
distribute 5/6 to each number
![5/6x + 5/12 + 10/3](https://tex.z-dn.net/?f=5%2F6x%20%2B%205%2F12%20%2B%2010%2F3)
change the fraction 10/3 so that it will have the same denominator as 5/12
= 40/12
![5/6x + 5/12 + 40/12\\5/6x + 45/12](https://tex.z-dn.net/?f=5%2F6x%20%2B%205%2F12%20%2B%2040%2F12%5C%5C5%2F6x%20%2B%2045%2F12)
divide both sides by 5/6
![x = 9/2](https://tex.z-dn.net/?f=x%20%3D%209%2F2)
![5/6*9/2+5/12+10/3 = \frac{15}{2}](https://tex.z-dn.net/?f=5%2F6%2A9%2F2%2B5%2F12%2B10%2F3%20%3D%20%5Cfrac%7B15%7D%7B2%7D)
Answer:
See explanation
Step-by-step explanation:
Given ![\triangle ABC\cong \triangle ADC](https://tex.z-dn.net/?f=%5Ctriangle%20ABC%5Ccong%20%5Ctriangle%20ADC)
According to the order of the vertices,
- side AB in triangle ABC (the first and the second vertices) is congruent to side AD in triangle ADC (the first and the second vertices);
- side BC in triangle ABC (the second and the third vertices) is congruent to side DC in triangle ADC (the second and the third vertices);
- side AC in triangle ABC (the first and the third vertices) is congruent to side AC in triangle ADC (the first and the third vertices);
- angle BAC in triangle ABC is congruent to angle DAC in triangle ADC (the first vertex in each triangle is in the middle when naming the angles);
- angle ABC in triangle ABC is congruent to angle ADC in triangle ADC (the second vertex in each triangle is in the middle when naming the angles);
- angle BCA in triangle ABC is congruent to angle DCA in triangle ADC (the third vertex in each triangle is in the middle when naming the angles);
Answer:
JL = 78
Step-by-step explanation:
MN is a midsegment. Based on the midsegment theorem,
MN = ½(JL)
MN = 5x - 16
JL = 4x + 34
Plug in the value
5x - 16 = ½(4x + 34)
5x - 16 = ½*4x + ½*34
5x - 16 = 2x + 17
Collect like terms
5x - 2x = 16 + 17
3x = 33
Divide both sides by 3
x = 11
✔️JL = 4x + 34
Plug in the value of x
JL = 4(11) + 34
JL = 44 + 34
JL = 78
Answer:
x = 18, y = 45
Step-by-step explanation:
4x - 7 + a = 180 (linear pair)
But, a = 6x + 7 (alternate interior angles)
=> 4x - 7 + 6x + 7 = 180
=> 10x = 180
=> x = 18
Now, 3y - 20 = 6x + 7 (vertically opposite angles)
=> 3y - 20 = 6(18) + 7
=> 3y = 108 + 7 + 20
=> 3y = 135
=> y = 45
Hope it helps :)
