The body of a 154-pound person contains approximately 2 x 10^-1 milligrams of
gold and 6 x 10^1 milligrams of aluminum. Based on this information, the number of
milligrams of aluminum in the body is how many times the number of milligrams of gold
in the body?

i got so much points from yo a.

2.14x - 12.18 = -5.76

add 12.18 to each side

2.14x -12.18 +12.18 = -5.76 +12.18

2.14 x =6.42

divide by 2.14

2.14x/2.14 = 6.42/2.14

x=3

lr = 24

step-by-step explanation:

note that p is the midpoint of lr. to find the measurement of lr, set the equation:

lr = lp + pr

plug in the corresponding numbers to the corresponding variables:

lr = (15) + (9)

simplify:

lr = 24

24 is your measurement of lr.
