Answer:

How many centimeters of string does she need?

30 * 30 cm = 900 cm

If the total cost of the string was $4.41, how much did she spend per meter?

4.41 / 9 = $0.49 per meter

So 30 necklaces with 30cm of string each, and the total cost was $4.41, but we have to find out how much each meter cost. Wow this problem is a little confusing.

To find the total centimeters of string she needs, we do 30 x 30, which is 900. So she needs 900cm of string.

Now, we have to find how much string is per meter. 1 meter is 100cm, and we know that she needs 900cm, so she needs 9 meters of string. Now, we divide 4.41 by 9, giving us 0.49.

So she needs 900cm of string, and it costs $0.49 per meter.

Is x a solution to 80<-9x+8

Answers: $x$

1. Switch sides

$-9x+8>80$

2. Subtract by 8 from both sides of equation.

$-9x+8-8>80-8$

3. Simplify.

$-9x>72$

4. Multiply by -1 from both sides of equation. (it's should be the reverse inequality).

$(-9x)(-1)$

5. Simplify.

$9x$

6. Then you had to divide by 9 from both sides of equation.

$\frac{9x}{9}< \frac{-72}{9}$

7. Simplify.

$\frac{9x}{9}=x$

8. Divide by the numbers.

$\frac{9}{9}=1$

$=x$

$\frac{-72}{9}=-8$

9. Divide by the numbers.

$\frac{72}{9}=8$

$=-8$

$x$
