Answer:
2000 = 600 + 2/5x ; 3500 ft
How To Solve:
2000 = 600 + 2/5x
Combine multiplied terms into a single fraction
2000 = 600 + 2/5x
2000 = 600 + 2x/5
Subtract 600 from both sides of the equation
2000 = 600 + 2x/5
2000 - 600 = 600 + 2x/5 - 600
Simplify
Subtract the numbers
1400 = 600 + 2x/5 − 600
Subtract the numbers
1400 = 2x/5
Solution
X = 3500
Answer:
Step-by-step explanation:
note:when you do perpendicular lines you must change the slope to the oppisite and reciporcal
2y+4x=12
2y-1/4x=12
1/4x+2y=12
Answer:
2x=1
Step-by-step explanation:
Use x for "a number"
x times 2 = 1
2x=1
which solves for 0.5 or 1/2
Answer:
sorry i dont understand either!!!
Step-by-step explanation:
Answer:
i) = 23 °C
ii) = 4.4° C
Step-by-step explanation:
i) The temperature on the surface of the planet.
At the surface of the planet the height is Zero
Therefore, X = 0
Thus; using the equation, the temperature, y will be;
y = 23 - 5x
y = 23 - 5(0)
<u> = 23 °C</u>
ii) the temperature change for every kilometer from the surface,
From the equation;
y = 23 - 5x
we take, y to be 1
Therefore;
1 = 23 -5x , subtracting 23 on both sides we get
-22 = -5x
x = -22/-5
<u> = 4.4° C</u>
