We want to use the Substitution method to solve
7x - 2y = 1 (1)
x - 2y = 1 (2)
From equation (1), obtain
2y = 7x - 1 (3)
Substitute (3) into (2).
x - (7x - 1) = 1
-6x + 1 = 1
-6x = 0
x = 0
From (3), obtain
2y = 7*0 - 1 = -1
y = -1/2
Answer: (0, -1/2) or x=0, y= -1/2.
P(3) = 1/6
Number of attempt = 400
P(3) = 1/6 x 400 = 66.67 times.
Therefore the frequency can be between (B) 64 to (C) 70 times.
Answer (B) 64 and (C) 70
Answer:
The smallest number is 14
Step-by-step explanation:
Answer:
1.05 inches
Step-by-step explanation:
As the stretch varies directly with the amount of weight it means that a decrease in weight result in a proportional decrease of stretch.
Answer:
Let the number of hours traveled by train be "x".
The x = the number of hours traveled by plane.
-------------------------------------------------
Equation:
train distance + plane distance = 1300 miles
50x + 275x = 1300
x(325) = 1300
x = 4 hours
