Francine burns 215 calories for every hour she works out. Which equation represents the relationship between x, the number of hours Francine works out, and y, the number of calories she
burns?

y * x

or

215 * x

y times x because y(number of calories) times x(number of hours) is the total abount of calories burned during the workout. you could substitute 215 for y because we know that y is 215.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
