Answer:

x = 12

Step-by-step explanation:

For this problem it is important to note that the sum of the two unknown angles' measurements is equivalent to the given known angle measurement as implied by the drawing.  With this in mind let's write our givens:

m<CGF = 10x - 10

m<HGC = 3x + 10

m<HGF = 156

So now let's form our equation to represent the drawing:

m<CGF + m<HGC = m<HGF

And now let's solve the equation to find the value of the x.

m<CGF + m<HGC = m<HGF

( 10x - 10 ) + ( 3x + 10 ) = 156

10x - 10 + 3x + 10 = 156

13x = 156

x = 12

Hence, our value for x is 12.

Cheers.

A car travels 2 1/3 miles in 3 1/2 minutes at a constant speed. Write an equation to represent the car travels in miles and minu
Korvikt [17]

Answer:

d = 0.666t , where d is in miles and t is in minutes.

d = 39.94h, where d is in miles and h is in hours.

Step-by-step explanation:

A car travels 2\frac{1}{3} = 2.33 miles in 3\frac{1}{2} = 3.5 minutes at a constant speed.

Let the relation between the distance (d) traveled by car in miles after traveling t minutes is d = kt ......... (1)

Now, putting d = 2.33 miles and t = 3.5 minutes in the above equation we get,

2.33 = 3.5k

⇒ k = 0.666 (Approx.)

So, the equation (1) becomes d = 0.666t. (Answer)

Let us assume that the relation between the distance (D) traveled by car in miles after traveling h hours is d = Kh ............ (2)

Now, putting D = 2.33 miles and T = 3.5/60 = 0.058 hours in the above equation, we get

2.33 = 0.058K

⇒ K = 39.94

So, the equation (2) we get, d = 39.94h (Answer)
