What is the solution to this inequality?<br>4(2x + 2) + 12 &gt; 100<br>please help!!​
skad [1K]

Subtract 12 from both sides

4(2x + 2) > 100 - 12

Simplify 100 - 12 to 88

4(2x + 2) > 88

Divide both sides by 4

2x + 2 > 88/4

Simplify 88/4 to 22

2x + 2 > 22

Subtract 2 from both sides

2x > 22 - 2

Simplify 22 - 2 to 20

2x > 20

Divide both sides by 2

x > 20/2

Simplify 20/2 to 10

<u>x > 10</u>

Identify the type of sequence 1/10, 3/20, 5/30, 7/40...
Dafna11 [192]
Arithmetic sequence: must have a constant common difference.
3/20-1/10=(3-2)/20=1/20
5/30-3/20=(10-9)/60=1/60
Difference is not constant, so no.

Geometric sequence: must have a common ratio
30/20 / (1/10) = 15
5/30 / (3/20) = 100/90 = 10/9 
ratio is not constant, so no.

The answer is (c) neither geometric nor arithmetic
