Answer:
∠QPT=122°
Step-by-step explanation:
Angles along a straight line add up to 180. Therefore:
∠PRQ+∠PRS=180
∠PRQ+118=180
∠PRQ=180-118
∠PRQ=62°
All angles in a triangle add to 180. Therefore:
∠PQR+∠QPR+∠PRQ=180
60+∠QPR+62=180
∠QPR+122=180
∠QPR=58°
Angles along a straight line add to 180. Therefore:
∠QPT+∠QPR=180
∠QPT+58=180
∠QPT=122°
Distribute 1/2 throughout the set of parenthesis
1/2 · x = 1/2x
1/2 · 12 = 6
1/2x + 6 = 4x -1
subtract 6 on both sides of the equation
1/2x = 4x - 7
subtract 1/2x by 4x
4x - 1/2x = 7/2x
7/2x = -7
isolate x by dividing both sides by 7/2
Which is actually multiplying by the reciprocal, which is 2/7
-7 · 2/7 = -14/2 = -7
x = -7
So, only one answer/solution
0.5 repeating as a fraction can be written as 5/9
