For what value of X must ABCD be a parallelogram?

Solution:

We know that:

This means that:

Step-by step calculations:

Simplify the RHS:

Subtract 13x both sides:

Divide -1 both sides:

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

constants mean the stopped points or the points on a graph that nothing is changing, hope this
