In quadrilateral abcd the measures of the angles are represented by measure angle a=6x-2, measure angle b=6x+5, measure angle c=
OleMash [197]

\bf \textit{sum of all interior angles in a polygon}\\\\ S = 180(n-2)~~ \begin{cases} n=\stackrel{number~of}{sides}\\[-0.5em] \hrulefill\\ n = \stackrel{quadrilateral}{4} \end{cases} \\\\\\ \stackrel{\measuredangle a}{(6x-2)}~~+~~\stackrel{\measuredangle b}{(6x+5)}~~+~~\stackrel{\measuredangle c}{(8x+2)}~~+~~\stackrel{\measuredangle d}{(3x+10)}~~=~~180(4-2)

\bf 23x+15=180(2)\implies 23x+15=360\implies 23x=345 \\\\\\ x = \cfrac{345}{23}\implies \boxed{x = 15} \\\\\\ \stackrel{\measuredangle c}{8x+2}\implies 8(15)+2\implies 122

What is the domain of the function represented by the graph?
Natalija [7]

The domain of given function is: -3≤x≤3

Step-by-step explanation:

The domain is the set of all possible inputs of the graph. In a graph, the input values are plotted on x-axis and the output or range is plotted on y-axis.

In the given figure we can see that the x-values that are involved in the graph of function are between -3 and 3. So the domain of the function will be:

-3≤x≤3

Hence,

The domain of given function is: -3≤x≤3

Keywords: Domain, Range

David hikes 21/4 miles in 1/2 an hour. What is his rate in miles per hour? At this rate, how long will it take him to walk 18 mi
harkovskaia [24]

Answer:

A) speed = 10.5 miles per hour

B) Time taken by him = 1.714 hours

C)  Distance = 10.5 mph × 7 hours = 73.5   miles

Step-by-step explanation:

Given as :

The distance cover by David = \frac{21}{4} miles = 5.25 miles

The time taken by David        = \frac{1}{2}  hours  = 0.5 hours

Let the speed                          = x mile per hour

So, Distance = Speed × Time

A)or,  Speed = \frac{Distance}{Time}

Or,  Speed = \frac{5.25}{0.5}

∴     speed = 10.5 miles per hour

<u>B) Again The Distance cover by him = 18 miles</u>

SO, with speed 10.5 miles per hour

The Time taken by him =  \frac{Distance}{speed} hours

Or, Time taken by him =  \frac{18}{10.5} hours

∴    Time taken by him = 1.714 hours

<u>C) Again the Time taken by him = 7 hours   </u>

So, Distance cover by him with speed 10.5 mph

Or, Distance = 10.5 mph × 7 hours = 73.5   miles

A) speed = 10.5 miles per hour

B) Time taken by him = 1.714 hours

C)  Distance = 10.5 mph × 7 hours = 73.5   miles   Answes

Jada Elena and Lin walked a total of 37 miles last week. jada walked 4 more miles that elena, and Lin walked 2 more miles than j
MA_775_DIABLO [31]

Answer:

Jada walked 13\ miles

Elena walked 9\ miles

Lin walked 15\ miles

Step-by-step explanation:

Let

x----> total miles walked by Jada

y----> total miles walked by Elena

z----> total miles walked by Lin

we know that

x+y+z=37 -----> equation A

x=y+4 -----> y=x-4 ------> equation B

z=x+2 ------> equation C

Substitute equation C and equation B in equation A and solve for x

x+(x-4)+(x+2)=37

3x=37+2

3x=39

x=13\ mi

Find the value of y

y=13-4=9\ mi

Find the value of z

z=13+2=15\ mi

therefore

Jada walked 13\ miles

Elena walked 9\ miles

Lin walked 15\ miles
