Answer:
4/15 is your answer my friend
Step-by-step explanation:
Equations don't equal numbers.
Sometimes their solutions, if they have one, do.
Here are three equations whose solutions are 36 :
x + 15 = 51
x/3 = 12
x² - 72x + 1,296 = 0
Replace y with 0 and solve for x.
x= -1.52138
Answer:
The temperature in degrees Celsius is <em>-48°C </em>.
Step-by-step explanation:
The given equation is:
v = 20√[t + 273]
Therefore, rearranging we get:
(v / 20)² = t + 273
t = (v / 20)² - 273
but the speed of sound, v, is equal to 300 m/s
Therefore,
t = (300 / 20)² - 273
<em>t = -48°C</em>
<em></em>
Therefore, the temperature in degrees Celsius is <em>-48°C </em>.
Answer:
e = 6
Step-by-step explanation:
Step 1: Write equation
-2(8 - e) = 2 - e
Step 2: Solve for <em>e</em>
- Distribute -2: -16 + 2e = 2 - e
- Add e to both sides: -16 + 3e = 2
- Add 16 to both sides: 3e = 18
- Divide both sides by 3: e = 6
Step 3: Check
<em>Plug in e to verify it's a solution.</em>
-2(8 - 6) = 2 - 6
-2(2) = -4
-4 = -4
