I think the answer is 120.
(Hope this helps ;3)
The first one, the fourth one, and the middle one
Need to see the graph first before answering!
Answer:
PR = 15
Step-by-step explanation:
PR = PQ + QR
10x - 45 = 3 + x + 6 {Combine like terms}
10x - 45 = 9 + x {Subtract 'x' from both sides}
10x - x - 45 = 9
9x - 45 = 9 {Add 45 to both sides}
9x = 9 +45
9x = 54
x = 54/9
x = 6
PR = 10x - 45
= 10*6 - 45
= 60 - 45
PR = 15
Answer:
x = 3
Step-by-step explanation:
You can see that 5x - 7 and 2x + 2 are equal to each other due to the arrows pointing to both angles. Therefore allowing you to set up the following equation..
5x - 7 = 2x = 2
Therefore you can then simplify for the value x where you should get teh value 3.
