Kyle is training for a marathon. the equation y = 3x + 5.5 represents the number of miles kyle can run over time, where y is the number of miles kyle runs and x is the number of weeks kyle has been training.
• how long will it take kyle to be ready to run the entire marathon of 26.5 miles?

Substitute the length of marathon into y.
26.5= 3x + 5.5

Solve for x (because that’s the amount of weeks needed to be ready and prepared)

3x = 26.5 - 5.5
3x = 21
x = 7
7 weeks of training is needed

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
