What is the solution to this equation? 7x-3(x-6)=30

Step-by-step explanation:

7x-3(x-6)

    -3(x) and -3(-6) (distribute)

7x-3x+18

7x-3x = 4x (common variables)

4x+18 = 30

     -18    -18 (gotta get that x alone)

4x = 12

4x/4 = 12/4 (get x alone)

x = 3

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
