He gained weight at a rate of 5.5 kilograms per month.Let y represent the sumo wrestler's weight (in kilograms) after x months.Complete the equation for the relationship between the weight and number of months.y=□
Q. A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly. After 11 months, he weighed 140 kilograms. He gained weight at a rate of 5.5 kilograms per month.Let y represent the sumo wrestler's weight (in kilograms) after x months.Complete the equation for the relationship between the weight and number of months.y=□
Find initial weight: Identify the initial weight of the sumo wrestler.The sumo wrestler's weight after 0 months is the initial weight, which we need to find. We know that after 11 months, he weighs 140 kilograms, and he gains weight at a rate of 5.5 kilograms per month. To find the initial weight, we subtract the total weight gained from the weight after 11 months.Initial weight = Weight after 11 months − (Weight gain per month × Number of months)Initial weight =140kg−(5.5kg/month×11months)Initial weight 110Initial weight 111
Write equation for weight after x months: Write the equation for the sumo wrestler's weight after x months.We know that the sumo wrestler gains 5.5 kilograms each month. Therefore, the weight of the sumo wrestler after x months can be represented by the initial weight plus the weight gained over x months.y= Initial weight +(Weight gain per month ∗ Number of months)y=79.5 kg x0 kg/month x1
Check equation for errors: Check the equation for any mathematical errors.We have the initial weight as 79.5kg and the weight gain per month as 5.5kg. Multiplying the weight gain per month by the number of months (x) and adding it to the initial weight gives us the sumo wrestler's weight after x months.y=79.5+5.5xThis equation correctly represents the relationship between the sumo wrestler's weight and the number of months.
