Answer:

x=2

Step-by-step explanation:

Step-by-step explanation:

a straight line equals to 180

27x+42+23x+38=180

(combine like terms)

50x+80=180

(subtract 80 from 180)

50x=100

(divide 50 by 100)

Answer:

x = 2

Step-by-step explanation:

Since these two angles are complimentary, that means that they add up to 180 degrees.

<u>Step 1:  Make an equation </u>

<em>(27x + 42) + (23x + 38) = 180 </em>

<u>Step 2:  Combine like terms </u>

<u>27x</u> + 42 + <u>23x</u> + 38 = 180

<em>50x + 80 = 180 </em>

Step 3:  Subtract 80 from both sides

50x + 80 - 80 = 180 - 80

50x = 100

Step 4:  Divide 50 from both sides

50x / 50 = 100 / 50

<em>x = 2 </em>

Answer:  x = 2

What is the rate of change of the water level , in feet per hour
miskamm [114]
A; rate of change is the same as slope, so, using the slope formula, m= \frac{y_{2} - y\1_{1}   }{ x_{2} - x_{1} }, where m is the slope and x_{1}, x_{2}, y_{1}, and y_{2} are the x and y values.

Plug in 2 points for x and y, water level being the y and time being the x since we're looking for the answer in ft/hr-- you can choose any two, but from the same row.

m= \frac{ 30-50}{4-0}
m= \frac{-20}{4}
m= \frac{-5}{1}
m= -5 ft/hr
