Answer:
5 marbles
Step-by-step explanation:
Assume the first is color 1
and then the second is color 1
Now the third is color 2
The fourth is color 2
Now the 5th marble of either color will make 3 of one color

(i)
12x+ 7 = 6x + 27
12x-6x = 27-7
6x = 20
x = 20/6 =10/3 = 3.33
(ii)
4x + 74 = 9x = +14
4x - 9x = 14 -74
-5x = -60
x = -60/ -5 = 12.
(iii)
12x -14 = 9x -1
12x-9x = -1 +14
3x = 13
x = 13/3
(iv) 3x + 35 = 13x -45
3x -13x = -45 - 35
- 10x = - 80
x = -80/-10= 8
(v)
6x -1 = 16x -121
6x -16x =-121+1
-10x = -120
x = -120/-10 = 12
(vii)
10 + 9x = 42 + x
9x - x = 42 -10
8x = 32
x = 32/8 =4
The answer would be 416.666666667
Smaller angle = 41°
Larger angle = 139°
Step-by-step explanation:
(7x - 1) + (2x + 1) = 180
7x + 2x - 1 + 1 = 180
9x = 180
x = 20
- The measure of the smaller angle is
2x + 1
= 2(20) + 1
= 40 + 1
<u>= 41°</u>
- The measure of the larger angle is
7x - 1
= 7(20) - 1
= 140 - 1
<u>= 139°</u>
