Lorena determined that she weighs 3 pounds more than 4 times the weight of her baby brother Omar. She represented her weight with the expression \(4x + 3\), where \(x\) is Omar's weight. If Lorena weighs 67 pounds, how many more pounds does Lorena weigh than Omar?

Answer :

Final answer:

Lorena weighs 51 pounds more than her baby brother Omar, with Omar weighing 16 pounds and Lorena weighing 67 pounds.

Explanation:

Lorena weighs 67 pounds, which is represented by the expression 4x+3, where x is Omar's weight. To find Omar's weight, we solve the equation 4x+3 = 67. Subtracting 3 from both sides gives us 4x = 64, and dividing both sides by 4 gives us x = 16. Omar weighs 16 pounds, and Lorena weighs 67 pounds. To determine how many more pounds Lorena weighs than Omar, we subtract Omar's weight from Lorena's weight: 67 - 16 = 51. Therefore, Lorena weighs 51 pounds more than Omar.

Answer: Lorena weighs 51 lbs more than Omar.

Step-by-step explanation: Set 4x+3 equal to 67, Lorena's weight. This makes sense because the x in 4x+3 represents Omar's weight.

4x+3=67

4x=64

x=16

The question asks for the difference between Omar and Lorena's weight, so simply subtract the two numbers.

67-16=51
