Evgen [1.6K]3 years ago

Answer:

g(3)=31.5-3

Step-by-step explanation:

first you want to find g(1) or g(x). all you have to do for this is divide every number by two, since 2/2 is 1.

g(1)=10.5-1

now to find g(30 you just multiply it all by 3.

g(3)=(10.5-1)*3

g(3)=31.5-3.

Daniel rollerbladed 3 miles in 12 minutes what was his speed in miles per hour
a_sh-v [17]

Daniel is rollerblading at 15 miles per hour


Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15


Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15

The average age of 4 children is 15 yrs . if the ages of their parents are added , their average age is 25 .find the age of thei
WITCHER [35]

The age of the father is 57 years old

<h3>Calculating mean of a population</h3>

Total age = Average age x Population

Average of the four children = 15

Population = 4

Total age of the four children = 15 x 4

Total age of the four children = 60 years

If the parents are added:

Population = 6

Average age = 25

Total age = 25 x 6

Total age = 150 years

Total age of the parents = 150 - 60

Total age of the parents = 110 years

The father is 4 years older than his wife

Let the age of the father be x

The age of the wife = x - 4

x + x - 4 = 110

2x = 114

x = 114/2

x = 57

Therefore, the age of the father is 57 years old
