3x - 5y = 5 ——> 6x - 10y = 10
6x - 10y = 10
x + 10y = 4
——————-
5x = 6
x = 1.2
1.2 + 10y = 4
10y = 2.8
y = 0.28
so, x = 1.2 and y = 0.28
hope this helps :)
Answer:
0=24 so theirs no solution
Step-by-step explanation:
Answer:
When A and B are not both zero, the graph of Ax + By = C is always a line. The graph of Ax + By = C, where A and B are not both zero, is a line. Divide both sides by B. Because the form Ax + By = C can describe any line, it is called the standard form of an equation for a line.
Hope this helps you!
Answer:
2.60
Step-by-step explanation:
z-score is the difference between the score and mean, divided by the standard deviation.
So 2.6 is an answer close enough.
Answer:
If 2 mph) 5 hours
If 2.5 mph) 4 hours
If m mph) 10/m hours
If m+2 mph) 10/(m+2) hours
If m/3 mph) 30/m hours
Step-by-step explanation:
To find the time divide the distance (10) by the speed.
10/2=5
10/2.5=4
10/m
10/(m+2)
10/(m/3)=10(3/m)=30/m
