Find the solution to the equation 4r + 2(r - 8) = 4(3 + r).

o-na [289]

Answer:

r = 14

Step-by-step explanation:

Use distributive property:

4r + 2r - 16 = 12 + 4r

Combine like terms:

6r - 16 = 12 + 4r

Isolate the variable:

6r = 28 + 4r

2r = 28

r = 14

The table shows the temperatures in degrees Celsius, y, inside a shed at x hours past noon. The maximum and minimum temperatures

kolbaska11 [484]

Answer:

y = 3 cos (pi/12x - pi/4) + 17

Step-by-step explanation:

First find the average temperature which is 20 + 14/2 = 17

Find the amplitude

20 - 17 = 3

This means that that at noon, the shift is 3hrs past

the best equation that represents this scenario is $y = 3 cos (\frac{\pi}{12}x - \frac{\pi}{4}) + 17$

A man sold his house for $125,000. After paying he broker his commission, the man received $116,875. What was the broker’s commi

PilotLPTM [1.2K]

116875 = (x / 100) * 125000

116875 = x * 125000 / 100

116875 = 1250x (The zeros get cancelled)

Therefore, x = 116875/1250 = 187/2 = 93.5%
