<h3>The value of x is 4.10</h3>

<em><u>Solution:</u></em>

Given that,

The angle Johnny holds his pen on paper creates a linear pair

Angles in a linear pair are supplementary angles

Two angles are supplementary, when they add up to 180 degrees

The measure of one angle is 13x + 7

The  measure of the second angle is one less than twice the first angle

Therefore,

Measure of second angle = twice the first angle - 1

Measure of second angle = 2(13x + 7) - 1

Measure of second angle = 26x + 14 - 1

Measure of second angle = 26x + 13

Therefore,

Measure of first angle + measure of second angle = 180

13x + 7 + 26x + 13 = 180

39x + 20 = 180

39x = 180 - 20

39x = 160

x = 4.1

Thus value of x is 4.10

PLEASE HELP
s344n2d4d5 [400]
Let the length of the diameter be d and radius be r, thus to solve for d we proceed as follows:
r²+31²=(r+15)²
solving for d we solve for r
r²+961=r²+30r+225
putting like terms together we obtain:
r²-r²+961-225=30r
736=30r
solving for r
r=24.53
thus
d=24.5333×2
d=49.067~49.1
Answer is D. 49.1

Using the inequity -16k-32&gt;-48
3241004551 [841]

Answer:

k<1

Step-by-step explanation:

1. Add 32 to both sides

-16k-32+32>-48+32

2. Simplify

-16k>-16

3. Reverse the sign (You only reverse the sign if you are DIVIDING BY a negative.)

-16k/-16 = k

-16/-16 = 1

You're left with k < 1

Your number line graph should be an open circle at 1 going to the left.

Someone please help <br> WILL GIVE BRAINLIEST
Flauer [41]

Answer:

y=3x+1

Step-by-step explanation:

I'm very bad at explaining things so im sorry if this doesn't make any sense

the y axis goes up

the x axis goes sideways

to fill in the "y = ____x+_____"

you find a point on the line, see how far up it is from 0,0 and put that in the first blank space, in this case its 3. then you find how much it goes over on the x axis. in this case its 1 over. so you would put 1.

An airplane flying into a headwind travels the 1890-mile flying distance between two cities in 3 hours. On the return flight, th
aksik [14]

Answer:

Velocity (against wind) = 1,890 / 3 = 630 mph

Velocity (with the wind) = 1,890 / 2.5 = 756 mph

Plane speed (still air) = 630 + wind speed

Plane speed (still air) = 756 - wind speed

Adding both equations equals

2 * Plane speed (still air) = 1,386

Plane Speed = 693 mph
