2 1/2x - 3/4(2x+5)=3/8 3/8=0.375
2.5x - 0.75(2x+5)=0.375
2.5x - 1.5x - 3.75 = 0.373
2.5x-1.5x=4.12
1x=4.12
X= 4 1/8
Based on the scenario, the case must be filled like this :
blue/green/black x blue/ green/black x blue/green/black x random x random
Different ways he can arrange it :
3 x 5!/(2!x2!) + 3x <span>5!/3!
</span>
90 + 60
= 150 ways
hope this helps
Answer:
5
Step-by-step explanation:
5
There is no solution for the first one
if you eliminate y you get 2 equations
-13x - 13z = -25
-13x - 13x = -15
- there is no solution to theses
a23 means the element in the second row and the 3rd column
so its -5
