-2 -8 is the answer for this question x=-2 and x=-8
Answer:
Value of ![x=30](https://tex.z-dn.net/?f=x%3D30)
Step-by-step explanation:
When the two lines being crossed are Parallel Lines the Corresponding Angles are equal.
Hence
![x+25=55\\\\x=30](https://tex.z-dn.net/?f=x%2B25%3D55%5C%5C%5C%5Cx%3D30)
Answer:
5
Step-by-step explanation:
13 9/12 divided by 2 9/12
= 13 3/4 divided by 2 3/4
= 55/4 divided by 11/4
= 5
Answer:
RS = - 7
ST = - 13.5 = - 13½
RT = - 20.5 = - 20½
Step-by-step explanation:
From the question given above, the following were obtained:
RS = 6y + 2
ST = 15y + 9
RT = 5y - 13
To obtain RS, ST and RT, we must first obtain the value of y. This can be obtained as follow:
From diagram above, it is evident that:
RT = RS + ST
RS = 6y + 2
ST = 15y + 9
RT = 5y - 13
5y - 13 = 6y + 2 + 15y + 9
5y - 13 = 6y + 15y + 2 + 9
5y - 13 = 21y + 11
Collect like terms
5y - 12y = 11 + 13
- 16y = 24
Divide both side by - 16
y = 24/ - 16
y = - 1.5
Finally, we shall determine RS, ST and RT as follow:
RS = 6y + 2
y = - 1.5
RS = 6(-1.5) + 2
RS = - 9 + 2
RS = - 7
ST = 15y + 9
y = - 1.5
ST = 15(-1.5) + 9
ST = - 22.5 + 9
ST = - 13.5 = - 13½
RT = 5y - 13
y = - 1.5
RT = 5(-1.5) - 13
RT = - 7.5 - 13
RT = - 20.5 = - 20½
