five more than the product of a number n and 8 is at least 100. Write an inequality that can be used to find all positive values

hjlf

"More than" indicates addition, and "product" indicates multiplication.

The inequality is:

5 + 8n >= 100

Now we can solve for all positive values of n:

5 + (-5) + 8n >= 100 + (-5)

8n >= 95

8n/(8) >= 95/(8)

n >= 11.875

So all positive values of n include everything between 11.875 and positive infinity, inclusively.

Find a number in the sequence<br><br> 1) 100, 400, 610, ?, 652<br><br> 2) 342, 128, ?, 26

dsp73

Answer:

1. 460

2. 216

Step-by-step explanation:

From the series ,

100 , 400 , 610 , ? , 652

Writing the the digits in the revere order , i.e

001 , 004 , 016 , ? , 256

Now,

Now , getting the number in the form of the multiple of 4 as -

1 , 1 * 4 = 4 , 4 * 4 = 16 , ? , 64 * 4 = 4

Hence , the value for ? = 16 * 4 = 64 .

Again , reversing 64 to get the missing number of the series -

460 .

Hence ,

The value for ? is 460 .

From the series ,

342 , 128 , ? , 26

Now, multiplying the first digit with the second digit and merging it to the product of the second and third digit -

3 * 4 and 4 * 2 , 1 * 2 and 2 * 8 , ?

128 , 216 , ?

Hence ,

The value for question mark = 1 * 2 and 1 * 6 = 216

Hence ,

The value for ? is 216 .
