This is confusing:
This proportion can be changed to (0.45)y = x, where x represents the person's weight in kilograms and y represents the person's weight in pounds. The recommended protein in grams is numerically equal to the person's weight in kilograms.
If a man intakes 65 g of protein daily, his recommended intake, how much does he weigh in pounds?
Weight in pounds (to the nearest pound) = ?
thank you
To find the weight in pounds, we can use the equation (0.45)y = x, where x represents the person's weight in kilograms and y represents the person's weight in pounds.
In this case, we know that the recommended protein intake, which is numerically equal to the person's weight in kilograms, is 65 grams. So, we can set x = 65.
Now, we can solve the equation (0.45)y = 65 for y to find the weight in pounds. Here are the steps:
1. Divide both sides of the equation by 0.45:
(0.45)y / 0.45 = 65 / 0.45
2. Simplify the left side of the equation:
y = 65 / 0.45
3. Calculate the right side of the equation:
y ≈ 144.44
Therefore, the man's weight in pounds is approximately 144.44 pounds (to the nearest pound).
.45y = 65
y = 144
