Answer: D

Step-by-step explanation:

We are given X = 15 - 4y so simply replace any and all X's in the first equation with (15 - 4y). Option D is the best because the X is removed and replaced with the proper writing.

Find the value of x ?
RUDIKE [14]

Answer:

x = 50

Step-by-step explanation:

add all terms and set sum equal to 360

the 'hint' of (n-2)180 determines how many degrees there are inside the polygon; if 'n' equals the number of sides and the polygon has 4 sides then sum of interior angles is (4-2)180 or 2x180 which is 360

x + 10 + 3x + x + 2x = 360

combine like terms to get:  7x + 10 = 360

                                             7x = 350

                                              x = 50

Wewaii [24]

33.4 kW/ hr is generated when the sky is cloudy and clear.

<u>Step-by-step explanation:</u>

Power generated per day when the sky is cloudy = 400 kW

Power generated per day when the sky is clear = 400 kW

Power generated per hour when the sky is cloudy or clear = $\frac{400}{24} = 16.7 kW

Power generated per hour when the sky is cloudy and clear = 16.7 + 16.7 = 33.4 kW
