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
