How do you solve -2/5x -9<9/10
Finger [1]

Answer:

x > -99/4

Step-by-step explanation:

I must assume that you meant (-2/5)x -9<9/10.

This inequality has 3 terms.  The LCD is 10.  Multiply each term by 10 and reduce the result:

10(-2/5)x - 10(9) < 10(9/10), or:

-4x - 90 < 9

Adding 90 to both sides results in:

-4x < 99

Here we must divide by a negative number (that is, by -4).  This requires reversing the direction of the inequality sign:

x > -99/4 is the final solution.

How many tens are in the number 1,384
Andre45 [30]
There are 8 tens in the number 1,384.

Each digit in the number has an equivalent value based on its placement in the number.

1,384 where:

1 is in the thousands value
3 is in the hundreds value
8 is in the tens value
4 is in the ones value

The extended form of 1,384 is:

1 x 1000 + 3 x 100 + 8 x 10 + 4 x 1 = 1,384

1,000 + 300 + 80 + 4 = 1,384

8 x 10 = 80 ; shows that there are 8 10s in the number with a product of 80.
