LCM(4, 8) = 8

\dfrac{3}{4}=\dfrac{3\cdot2}{4\cdot2}=\dfrac{6}{8}

9+\dfrac{3}{4}x=\dfrac{7}{8}x-10\ \ \ \ |-9\\\\\dfrac{6}{8}x=\dfrac{7}{8}x-19\ \ \ \ |-\dfrac{7}{8}x\\\\-\dfrac{1}{8}x=-19\ \ \ \ |\cdot(-8)\\\\x=152

Answer:

x = 75

y = 105

Step-by-step explanation:

Remark

You can find y in two different ways.

One

You can recall that y is the sum of the 2 interior angles not connected to it. Those angles are called the remote interior angles. Or

Two

You can add the three angles to 180 and solve for x. Then since x and y are supplementary, you can find y.

Solution

One

y = 60 + 45

y = 105                       Answer

Two

x + 60 + 45 = 180      All triangles have 180 degrees. Solve for x.

x + 105 = 180             Subtract 105 from both sides

x = 180 - 105              Combine

x = 75                         Find an equation that relates x and y

x + y = 180                 x and y are supplementary they add to 180

75 + y = 180               Subtract 75 from both sides.

y = 180 - 75                Combine

y = 105

HURRY PLS The length of time in hours of two airplane flights are represented by the following functions, where x is the number
mamaluj [8]

Answer:

h(x) = 0.0045x – 0.4

Step-by-step explanation:

The length of time in hours of two airplane flights are represented by the following functions, where x is the number of miles for the flight.

Flight A: f(x) = 0.003x - 1.2

Flight B: g(x) = 0.0015x + 0.8

Then the function  

h(x) = f(x) + g(x) = (0.003 + 0.0015)x + (-1.2 + 0.8) = 0.0045x - 0.4.

Therefore, the third option is the right option. (Answer)
