Answer:
9
Step-by-step explanation:
If x is the number of 10-inch stones, then (x-1) is the number of 5-inch stones, and the total width is ...
10x +5(x-1) = 130
15x -5 = 130 . . . . . . . eliminate parentheses
15x = 135 . . . . . . add 5
x = 9 . . . . . . . divide by 15

Need a picture! Then I will be happy to help :
Answer:
a. x = 180 - (j + k)
b.
j + k = (5x - 2) + (2x - 2) = 7x - 4
l = x
x = 180 - (7x - 4)
x = 180 - 7x + 4
8x = 184
x = 184/8
x = 23
l = 23°
j = 5x - 2
j = 5 × 23 - 2
j = 115 - 2
j = 113°
k = 2x - 2
k = 2 × 23 - 2
k = 46 - 2
k = 44°
<em>or k = 180 - (23 + 113) = 180 - 136 = 44°</em>
You can’t see it the picture isnt clear
