Answer:

$\frac{n}{3}-8=18$

Step-by-step explanation:

Eight less than the quotient of a number and 3 is 18.

Let the unknown number be 'n'

the quotient of a number and 3. For quotient we divide by 3

$\frac{n}{3}$

Eight less than the quotient of a number and 3

For eight less , we subtract 8 from the division

$\frac{n}{3}-8$

The above expression is equal to 18

Eight less than the quotient of a number and 3 is 18.

$\frac{n}{3}-8=18$

A salesperson is paid $140 per week plus 10% commission on her weekly sales of x dollars. Find a linear function that represents

Verizon [17]

Her weekly sales is X dollars

10% as a decimal is 0.10

Total commission is 0.10X ( 10% times weekly sales)

You then need to add that to her base pay of $140.

The equation is: w = 0.10x + 140

Answer:

(f ￮ g)(x) = $2^{x+1}$

Step-by-step explanation:

Substitute x = g(x) into f(x) , that is

= f(g(x))

= f(x + 1)

= $2^{x+1}$

Bob's truck averages 23 miles per gallon. If Bob is driving to his mother's house, 72 miles away, how many gallons of gas are ne

anyanavicka [17]

Answer:

3.1 gallons

Step-by-step explanation:

To solve this, we need to figure out how many gallons of gas go into 72 miles. We know 23 miles is equal to one gallon of gas, and given that the ratio of miles to gas stays the same, we can say that

miles of gas / gallons = miles of gas / gallons

23 miles / 1 gallon = 72 miles / gallons needed to go to Bob's mother's house

If we write the gallons needed to go to Bob's mother's house as g, we can say

23 miles / 1 gallon = 72 miles/g

multiply both sides by 1 gallon to remove a denominator

23 miles = 72 miles * 1 gallon /g

multiply both sides by g to remove the other denominator

23 miles * g = 72 miles * 1 gallon

divide both sides by 23 miles to isolate the g

g = 72 miles * 1 gallon/23 miles

= 72 / 23 gallons

≈ 3.1 gallons

Ther are 6 girls and 7 boys in a class. A team of 10 players is to be selected from the class. How many different combinations o

omeli [17]

Answer:

There are 286 possible combinations

Step-by-step explanation:

To solve this problem we must use the formula of combinations.

$nCr =\frac{n!}{r!(n-r)!}$

Where n is the number of players that there are and elect r of them

In this case there are 7 + 6 = 13 players and you choose 10 of them

Then we look for 13C10

$13C10 =\frac{13!}{10!(13-10)!}$

$13C10 =\frac{13!}{10!*3!}$

$13C10 =286$

There are 286 possible combinations
