Answer:
0.220 L
Step-by-step explanation:
One liter is 1000 mL, so 2,220 mL is 2.220 L. Subtracting the 2 L on hand gives the additional amount required:
2.220 L - 2 L = 0.220 L
_____
The nice thing about metric units is that conversion factors are often powers of 10, so only movement of the decimal point is required. It can be worthwhile to become familiar with the SI prefixes.
The fully factored polynomial is −3(x−6)(x+6).
Answer:
-36
Step-by-step explanation:
-(36/-6) to the power of 2 is -36.
Answer:
The equation that models the cost of each bracelet is
. Cost of each bracelet is $7.
Step-by-step explanation:
Let the cost of each bracelet is defined by the variable x.
Cost of 9 bracelet is 9x. The shipping cost is $9. Therefore the total cost of 9 bracelets, including shipping is

The total cost for 9 bracelets, including shipping is $72.

Subtract 9 from both sides


Divide both sides by 9.

Therefore the cost of each bracelet without shipping changes is $7.
Answer:
x = 0
Step-by-step explanation:
Step 1: Write equation
-19 = x - 19
Step 2: Solve for <em>x</em>
- Add 19 to both sides: 0 = x
- Rewrite: x = 0
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-19 = 0 - 19
-19 = -19
