Help please I’ll make it brainliest!!!!!

mr Goodwill [35]

Step-by-step explanation:

it is very simple, once you remember that "kilo" means 1000, "mili" means 1/1000, and "centi" means 1/100.

and therefore 1 cg = 10 mg, or 1 cm = 10 mm.

"deci" means 1/10.

and therefore 1 dm = 100 mm, 1dg = 100 mg.

9.32 kg = 9.32×1000 = 9320 g

1.429 g = 1.429/1000 = 0.001429 kg

287 g = 287/1000 = 0.287 kg

4.6 L = 4.6×1000 = 4600 mL

0.119 L = 0.119×1000 = 119 mL

9936 mL = 9936/1000 = 9.936 L

26793 mL = 26793/1000 = 26.793 L

0.06 L = 0.06×1000 = 60 mL

170 cg = 170×10 = 1700 mg

10.

2674 cm = 2674/100 = 26.74 m

11.

9.05 mm = 9.05/100 = 0.0905 dm

12.

2 L = 2×1000 = 2000 mL

13.

62.4 L = 62.4×1000 = 62400 mL

14.

99.9 mm = 99.9/1000 = 0.0999 m

15.

4.34 g = 4.34×100 = 434 cg

16.

10 km = 10×1000 m = 10×1000×1000 = 10000000 mm

17.

65 cL = 65/100 = 0.65 L

18.

105 mL = 105/1000 = 0.105 L

19.

0.27 g = 0.27×100 = 27 cg

20.

7777 m = 7777/1000 = 7.777 km

Melanie saves $20 every month in her savings account. She

OLga [1]

Let x represent the amount of months she has been saving for.

20x - 60 = 280

Solve for x.

20x - 60 = 280

~Add 60 to both sides

20x - 60 + 60 = 280 + 60

~Simplify

20x = 340

~Divide 20 to both sides

20x/20 = 340/20

~Simplify

x = 17

Therefore, Melanie has saved for 17 months.

Best of Luck!

What is the answer and how do you solve <br><br><br> 21x^3/3x^−1

Sunny_sXe [5.5K]

Answer:

as written: 7x^2

perhaps intended: 7x^4

Step-by-step explanation:

As written, the Order of Operations specifies that the only denominator factor is 3, so the expression is interpreted as ...

$\dfrac{21x^3}{3}x^{-1}=\dfrac{21}{3}x^{3-1}=7x^2$

___

Sometimes grouping of denominator factors is intended, but parentheses are not written as they should be. If the intention is ...

21x^3/(3x^-1)

then the simplification is ...

$\dfrac{21x^3}{3x^{-1}}=\dfrac{21}{3}x^{3-(-1)}=7x^4$

_____

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

a^b/a^c = a^(b-c)
