According to Newton's Second Law of Motion, the sum of the forces that act on an object with a mass m that moves in an acceleration a is equal to ma.
An object whose mass in 80 grams has an acceleration of 20 meters per seconds square.
kg. m
What calculation will give us the sum of the forces that act on the object, in Newtons

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

mean, 40.6
