For this case we have to:
x: Variable that represents Tyler's age
y: Variable that represents Tiffany's age
According to the data of the statement we can propose the following equations:
To solve we substitute the first equation in the second equation:
So, Tiffany is 14 years old.
Then Tyler has:
Tyler is 18 years old.
Answer:
Tyler: 18 years old
Tiffany: 14 years old
Answer:
3500.
Step-by-step explanation:
We have been given that Cesar Chavez lead a March with 6,300 people. The ratio of marchers who were not farm-workers to farm-workers is 4:5. We are asked to find the number of marchers, who were farm-workers.
First of all, we will find the ratio of farm-workers to total marchers as:
To find the number of marchers, who were farm-workers, we need to find of whole marchers.
Therefore, 3500 marchers were farmers.
