 Question 462338: 1. Each year, I plant a fruit/vegetable garden in the spring. I grow a variety of things, but my BIG plantings are of tomatoes and peppers. However, getting my seeds to sprout is not as easy as you’d think…. A. This year, I seeded both peppers and tomatoes, using a total of 120 seeds. Write an equation to show this. Using P for peppers and T for tomoatoes the equation would look like: P+T=120 B. I sowed nine times as many tomato seeds as pepper seeds. Write an equation to show this. 9T+P=120 C. How many tomato seeds did I plant? D. How many pepper seeds did I plant? I really do not want the answer I just want to know if I am on the right track as far as my equations go. I tried to solve using the substitution method but I keep coming up with T=0 and P=120 which I know can't be right, right? Click here to see answer by amoresroy(333)
