Answer:

third option

Step-by-step explanation:

There is a common difference d between consecutive terms in the sequence, that is

d = - 13 - (- 10) = - 16 - (- 13) = - 3

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 10 and d = - 3, then

[tex]a_{n}[/tex] = - 10 - 3(n - 1) = - 10 - 3n + 3 = - 7 - 3n

Thus the sum of the first 6 terms is represented by

∑ - 7 - 3n ( for n = 1 to 6 )

15x+10y>180

please solve

Answers

Answer:

x>12-(2y)/(3)

y>18-(3x)/(2)

Step-by-step explanation:

Answer:

The solution is:

x = 5

y = 11

Step-by-step explanation:

15x+10y>180

Since I know 15 + 10 = 25, I subtracted 25 from 180.

180 - 25 = 155

Therefore, we know that x and y multiplied by 15 and 10 must equal anything more than 180. Therefore, there are a variety of solutions. However, this is the one that I chose.

15(5)+10(11)>180

75+110>180

185>180 <----- This is a true statement.

solve for x !!!!!!!!

Answers

Answer:  x = 12

=====================================================

Work Shown:

I'm assuming the diagram shows that interior angles F and G are 24 and 12+5x respectively.

We can use the remote interior angle theorem to get:

(interior angle F)+(interior angle G) = exterior angle FEH

(24) + (12+5x) = 8x

5x+36 = 8x

36 = 8x-5x

36 = 3x

3x = 36

x = 36/3
