So if i have 5.40$ in my bank account on my fourth birthday, and my parents add 0.5$ each week, how long will it be until i'm able to get a car thats 24.99$? also show your work and dont guess and check, i'd love to know the equation.

5.40 + 0.5x = 24.99, x is the number of weeks.

- 5.40 - 5.40

0.5x = 19.59

/0.5 /0.5

x = 39.18

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'.
