A painter mixed 2 liters of red paint with every 5 liters of yellow paint in order to make an orange paint. Problem:
Which ratio of liters of red paint to yellow paint will make the same shade of orange paint?
can somebody help, its for a test please :(

The number of calories you burn depends on your weight. a 110-pound person burns 163 calories during 30 minutes of tennis. find the number of calories that a 190-pound person would burn during the same activity, assuming they burn calories at the same rate.
