Answer:

a) x = 10 + -1.5y

b) y+15

Step-by-step explanation:

a)2x+3y=10*√4

2x+3y=20

2x + 3y + -3y = 20 + -3y

2x + 0 = 20 + -3y

2x = 20 + -3y

x ÷ 2 = (20 + -3y) ÷2

x = 10 + -1.5y

b)x+2y+5*3=x+y

x+2y+15=x+y

x+2y+15 - y=x+y - y

x+y+15 =x

x+y+15 - x  =x - x

y+15

If an object has an acceleration of 7 m/s, and a mass of 3 kg, what is its force?
Anuta_ua [19.1K]

Answer:

force = 21 kg m/s^2 = 21 N

Step-by-step explanation:

If an object has mass (m)  3 kg, and its acceleration (a) is 7 m/s^2, its force is given by Newton's second law of motion: Force = M * a

Force = 3 kg * 7 m/s^2= 21 kg * m/s^2

This combinations of units (kg * m/s^2) is defined as Newtons in physics and abbreviated "N".

So we can say that the force on this object is of magnitude 21 N
