Answer:
11
Step-by-step explanation:
Let's call the white marbles w and the red marbles r. We can write:
w + r = 16 (1)
w = 3r - 4 (2)
3r - 4 + r = 16 (3) (Substitute (2) into (1))
4r = 20 (simplify)
r = 5 (divide by 4) which means w = 16 - 5 = 11
Answer:
x = 5
Step-by-step explanation:
6x - 3 = 3x + 12
-3x -3x
_____________
3x - 3 = 12
+3 +3
_____________
3x = 15
15 divided by 3 = 5
x = 5
You can double check this by replacing x with (5)
If it is right both sides should equal the same
6(5) - 3 = 3(5) + 12
30 - 3 = 15 + 12
27 = 27
This would prove that x = 5
156
Especially since the shape is convex
