4. 3(y + 4y) this is distributive property! Hope it helps. Btw can you please check out a question on my page? thanks!! <span />
The value of x must be 25.0. The correct option is the second option- 25.0
<h3>Solving Linear equations </h3>
From the question, we are to determine the value of x
From the given diagram, we can write that
m ∠SOR + m ∠UOR + m ∠TOU = 180° (<em>Sum of angles on a straight line</em>)
∴ (2x +8)° + (3x - 14)° + (3x -14)° = 180°
2x° + 8° + 3x° -14° + 3x° -14° = 180°
Collect like terms
2x° + 3x° + 3x° + 8° - 14° -14° = 180°
8x° -20° = 180°
8x° = 180° + 20°
8x° = 200°
x = 200/8
x = 25.0
Hence, the value of x must be 25.0. The correct option is the second option- 25.0

Answer:
or 3
Step-by-step explanation:
To find the slope find two coordinates and set up the equation
For the coordinates (0,2) and (2,8) y2 is 8 and y1 is 2. x2 is 2 and x1 is 0. you have to do subtraction first. 8-2 = 6 and 2-0 = 2
Now we have the equation
this can be simplified to
Let
be the amount of salt (in pounds) in the tank at time
. We're given that
.
The rate at which the amount of salt in the tank changes is given by the ODE
Given that
, we find that
so that the amount of salt in the tank is described by
The tank will be filled when
, or after
minutes. At this time, the amount of salt in the tank is
Answer:
