Answer:

x = 20

Step-by-step explanation:

45 + 4x = 6x + 5

45 - 5 =6x - 4x

40 = 2x

x = 40/2

x = 20

Check:

45 + 4*20 = 6*20 + 5

45 + 80 = 120 + 5 = 125

104 pounds requires 156 milligrams of medicine what is the weight of a patient who requires 207 milligrams of medicine

Lubov Fominskaja [6]

Answer:

138 pounds

Step-by-step explanation:

Let the required weight of the patient be x pounds.

We have that,

156 milligrams of medicine is required for a patient weighing 104 pounds.

Then, 207 milligrams of medicine will be required for a patient having weight as shown below,

Weight of the patient = $\frac{104 \times 207}{156}$

i.e. x = $\frac{21528}{156}$

i.e. x = $138$

Hence, the patient needing 207 milligrams of medicine will have the weight 138 pounds.
