Answer:

x = 54

Step-by-step explanation:

These angles are complementary because they add up to 90:

x - 7 + 43 = 90

x + 36 = 90

x = 90 - 36

x = 54

Answer:

Step-by-step explanation:

Since the total of the two degrees makes a right angle, we know that the unknown degree has to be 47

Knowing this, we can add 7 to this. (This is the inverse of subtracting to eliminate 7)

47 + 7 = 54

So <em>x</em> = 54

We can verify by solving replacing <em>x</em>.

(54 - 7) = 47

47 + 43 = 90

4) An arithmetic sequence has a 7th term of 54 and a 13th term of 94. Find the common difference

san4es73 [151]

Answer:

20/3

Step-by-step explanation:

Every nth term takes the form of a + n*d, where a is the first term.

So 7th term = (54 = a + 7d), 13th term = (94 = a + 13d).

equate them both:

94 - 13d = 54 - 7d

40 = 6d

d = 40/6

Which of the following values are solutions to the inequality -10_>6x-4

qaws [65]

Answer:

3rd option

Step-by-step explanation:

- 10 ≥ 6x - 4 ( add 4 to both sides )

- 6 ≥ 6x , then

6x ≤ - 6 ( divide both sides by 6 )

x ≤ - 1

Thus x = - 1 is a solution to the inequality
