To solve this expression, substitute 3 for x and simplify.
2(3)+3-6
By order of operations, we get 6+3-6, or 3.
Step-by-step explanation:
9) y= -2x - (5/2)
10) y = -5 + (5/2)
Answer:
Step-by-step explanation:
<u>Step 1: Add 9 to both sides
</u>
<u />
<u>Step 2: Divide both sides by 4
</u>

Answer:
Since you are looking for the speed, you need to rearrange the formula which is f = speed / wavelength. That should give you speed = f (wavelength.) All you need to do next is to substitute the value to the following equation. speed = 250 Hz (6.0m) that should leave you with 1500 m/s which is very fast.
