I WILL GIVE BRANLIEST IF YOU ANSWER THIS a grandfather is 9 times older than his granddaughter. In 8 years the grandfather will be 5 times older than his granddaughter. How old is each of them now? PLSSS I NEED QUICK:(

The granddaughter is 6 years old and the grandfather is 60 years old.

Step-by-step explanation: Present the age of the granddaughter as X years.

10x = x + 54

10x - x = 54

9x = 54

x = 54/9 = 6 years.

So, granddaughter’s age = 6 years and grandfather’s age = 10 x 6 = 60 years.

Hope this helps love! ^-^

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'.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
