Answer:
10 ways
Step-by-step explanation:
The number of ways in which five basketball players could be placed in three positions is:
5
= 
= 
= 
= 5 × 2
= 10
The basketball players can be arranged in 10 ways.
3.54 • 10*-2
Step-by-Step Solution:
Place the decimal point after the first non-zero number, and multiply by 10 to the appropriate power I.e., how many places you would need to move the decimal to get the original number.
Answer: 161.6 seconds
Step-by-step explanation:
1. 8.216 + 3.652 = 11.868 (add together, this is for one car)
2. 11.868 x 42 = 161.6

- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
- Solving systems of equations by graphing
Step-by-step explanation:
<u>Step 1: Define systems</u>
-5x - 3y = 12
y = x - 12
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: -5x - 3(x - 12) = 12
- Distribute -3: -5x - 3x + 36 = 12
- Combine like terms: -8x + 36 = 12
- Isolate <em>x</em> term: -8x = -24
- Isolate <em>x</em>: x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = x - 12
- Substitute in <em>x</em>: y = 3 - 12
- Subtract: y = -9
<u>Step 4: Graph systems</u>
