Answer:
Step-by-step explanation:
y -5x = 2
10x -3y =9
substitute x for 3/5 and y for -1
-1 -(5*3/5) = 2
(10*3/5) -3(-1) =9
simplify :
-1 -3 =2
6+3 =9
-4 =2 Not true
9=9 True
Conclusion: the point (3/5, -1) is not a solution to the given system of equations
Answer:
The rate of change is $15/day
Step-by-step explanation:
The rate of change, using the points (1,60) and (5,120)
m= (y2-y1) / (x2-x1)
= (120-60)/ (5-1)
= 60/4
= 15
The rate of change is $15/day
Answer:
GH 1533
Step-by-step explanation:
Let Dauda's share of the money=x
Patricia had twice as much as Dauda, therefore:
Patricia's share=2x
Luca had GH 600.00 more than Dauda, therefore:
Luca's Share =x+600
If Patricia had GH 2,000.00
Then: 2x=2000
x=1000
Therefore:
- Dauda's Share=GH 1000
- Patricia's share=GH 2000
- Luca's Share =1000+600=GH 1,600
Next, we determine the average share.

Total blocks = 35+47+22+21 = 125
Sum of red blocks and green blocks = 47+35 = 82
So the probability = 82/125 = 0.656
