Answer:
Step-by-step explanation:
In similar triangles, corresponding sides are in same ratio

Cross multiply,
7*(x + 8) = 6*(3x -9 )
7x + 7*8 = 6*3x - 6*9
7x + 56 = 18x - 54
56 = 18x - 7x -54
56 = 11x - 54
11x - 54 = 56
11x = 56 +54
11x = 110
x = 110 /11
x = 10
PR = 3x -9
= 30 - 9
PR = 21
Question 2 i think it’s the last one
question 5 i think it might be the second one
i’m not so sure though
Answer:

Step-by-step explanation:

First, we can work out 5% of our number, by multiplying it by 0.05

Now, if we add and subtract our 5% calculated from our original number, we can work out the minimum and maximum value that our final answer can be in the range of.
