Answer:
19.2 grams
Step-by-step explanation:
Assuming it is a straight proportion, then the givens are
w1 = 150 pounds
m1 = 24 grams
w2 = 120 pounds
m2 = x
m = medication amount.
w = weight
Equation
m1/w1 = m2/w2
Solution
24/150 = x / 120 Multiply both sides by 120
24 * 120/150 = x 120 /120
2880/150 = x Do the division
19.2 grams = x The amount the 120 pound woman should receive.

Answer:
5
Step-by-step explanation:
3(3x+7) = 3x+51
9x + 21 =3x+51 ; cuz 3 times 3 is 9 and 3 times 7 is 21
subtract 21 so 21 - 21 = 0 and 51 - 21 = 30 so
9x= 3x+30
Then subtract 3! 9-3x and 30 - 3x
You will get 6x = 30
Next you will divide by 6x
Lastly you will get 5! So your answer is 5, sorry it's a little messy but I hope this helps!
