There are 16 cards in each pile

Step-by-step explanation:

2. 14 3. 110 4. 71 5. 54 6. 16 7. 23

8. 75 9. 32 10. 22 11. 20 12. 48 13. 53

14. Spit 6 in half to get Melinda's length so the answer is 3

15. No the answer is not the same because you have to minus 18 to 8 (which is in the parenthesis) so the answer is 10. But the other way around you have to add 15 (which is in the parenthesis) plus 5.

I really hope I helped you

Y'all I am struggling Use the following functions to find each value below. f(x)=5x; g(x)=−2x+1; h(x)=x2+6x+8

Anni [7]

Answer:

see below the first three problems

Step-by-step explanation:

f(g(-2))

First, find g(-2) using function g(x). Then use that value as input for function f(x).

g(x) = -2x + 1

g(-2) = -2(-2) + 1

g(-2) = 5

f(x) = 5x

f(5) = 5(5)

f(5) = 25

f(g(-2)) = 25

g(h(3))

First, find h(3) using function h(x). Then use that value as input for function g(x).

h(x) = x^2 + 6x + 8

h(3) = 3^2 + 6(3) + 8 = 9 + 18 + 8

h(3) = 35

g(x) = -2x + 1

g(35) = -2(35) + 1 = -70 + 1

g(35) = -69

g(h(3)) = -69

f(g(3a))

First, find g(3a) using function g(x). Then use that value as input for function f(x).

g(x) = -2x + 1

g(3a) = -2(3a) + 1

g(3a) = -6a + 1

f(x) = 5x

f(-6a + 1) = 5(-6a + 1)

f(-6a + 1) = -30a + 5

f(g(3a)) = -30a + 5

suter [353]

Answer:

The expression representing the Total cost of 6 boxes is $6(3t + 2c)$ .

The Simplified expression representing the Total cost of 6 boxes is $18t + 12c$ .

Step-by-step explanation:

Given:

Number of thriller movies = 3

Number of Comedy movies = 2

Let the cost of thriller movie be t

Also Let the cost of comedy movie be c

Total Number of boxes = 6

Now, given a DVD box set includes 3 thriller movies and 2 comedies.

Cost of Each box = $3t + 2c$

We need to find the total cost of 6 boxes

Total Cost of 6 boxes is = $6(3t + 2c)$

Hence the expression representing the Total cost of 6 boxes is $6(3t + 2c)$ .

Simplifying the above expression we get;

Total Cost of 6 boxes is = $6(3t + 2c)= 6\times3t+6\times2c=18t+12c$

Hence the Simplified expression representing the Total cost of 6 boxes is $18t + 12c$ .
