So:
1000 meters = 1 kilometer,
So we can use the ratio 1km/1000m
Thus,
.007 kilometers*(1000m/1km) = 7 meters
So the equation is:
.007 kilometers = 7 meters
or
.007km = 7m
(a)

(b)we have 4 terms in this expression.
(c)+12 is the leading coefficient in

(d) constant is -45
To solve for x, you simplify both sides of the equation and then isolate the variable.
<em>10x + 12 = $72.00</em>
<em>x = 6</em>
