Answer:

21, 17, 13

Step-by-step explanation:

Find the mean of the 2 given values

mean = $\frac{25+9}{2}$ = $\frac{34}{2}$ = 17

Noe find the mean of 25 and 17 and 17 and 9

mean = $\frac{25+17}{2}$ = $\frac{42}{2}$ = 21 and

mean = $\frac{17+9}{2}$ = $\frac{26}{2}$ = 13

Thus the 3 means are 21, 17 and 13, that is

25, 21, 17, 13, 9

Answer:

The required expression for total cost: $0.17m+19.99d$

The cost for renting car for 2 days and driving 70 miles is $51.88

Step-by-step explanation:

Consider the table shown below which repented the required options.

Car Rental Prices :

Option 1 Option 2

$19.99 per day $50 fee

$0.17 per mi $0.17

Let d represents the number of days and m represents the number of miles.

you rent a car using option 1, For d days and m miles.

The required expression for total cost: $0.17m+19.99d$

Find the cost for renting car for 2 days and driving 70 miles

Substitute d=2 and m=70 in above expression.

$0.17(70)+19.99(2)$

$11.9+39.98$

$51.88$

Hence, the cost for renting car for 2 days and driving 70 miles is $51.88

m= 3-(-2)/ 3-0

m=5/3

y=mx+b

3= 5/3(3)+b

3= 5+b

-5 -5

Juan brought 4 Tshirts and leather jacket. The T shirts were all the same price, and the price of the leather jacket was 6 times

Alex

Let us say that:

x = the number of T shirts bought = 4

y = the number of leather jackets bought = 1

a = the price of the T shirts

b = the price of the leather jackets

With the given variables, we can say that the total cost is:

total cost = a x + b y

Since, b = 6 a, therefore:

total cost = a x + 6 a y

total cost = a (x + 6 y)

Since total cost is 209, therefore we can calculate for a since x and y are also given:

209 = a (4 + 6 * 1)

209 = a (10)

a = $20.9

Therefore each T shirt cost $20.9
