Answer:
see explanation
Step-by-step explanation:
Rearrange the equation expressing x or y in terms of the other variable.
2y = 4 - 3x ( divide both sides by 2 )
y =
Choose suitable values for x and evaluate for y
x = 2 → y = = = - 1
Thus (2, - 1 ) ← is a solution
x = - 2 → y = = = 5
Thus (- 2, 5 ) ← is a solution
x = 4 → y = = = - 4
Thus (4, - 4 ) ← is a solution
Answer: 31,020
Step-by-step explanation:
If the original price was 'p', the new price would be 'p - 10%p' or 'p - 0.1p'. We know this is equal to 305, so 'p - 0.1 p = 305' would be the equation.
Answer:
0.40m/s^2
Step-by-step explanation:
Given data
Mass= 133.5kg
Force F= 54.5N
The expression for the force acting is
F=ma
substitute
54.5=133.5*a
]Divide both sides by 133.5
a= 54.5/133.5
a= 0.40 m/s^2
Hence the acceleration is 0.40m/s^2
