Answer:

X= 7 I hope this helped!

Steps for equation/answer :

1.Divide both sides by 3.

4x+9= 111/3

2.Simplify 111/3 to 37.

4x+9=37

3.Subtract 9 from both sides.

4x=37−9

4. Simplify 37-9 to 28.

4x=28

5. Divide both sides by 4.

x = 28/4

6. Simplify 28/4 to 7

x=7

Answer:

Step-by-step explanation:

Known:

What to find = x

Exterior angle = 142

Right angle = 90

Unknown:

what unknown value is = ?

Interior angle = ?

1. Find the angle of the interior angles.

180 - 142 = 38

2. Add the two known angles

38 + 90 = 128

3. Subtract from 180

180 - 128 = 52

<h2>x = 52 is the answer.</h2>

Margarita [4]

X(x+18) <= 175
x^2+18x-175 <= 0 
(x+25)(x-7) <= 0 
So, -25 <= x <= 7

Find the measure Of K

Mariana [72]

Answer:

K = 10

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp/ hyp

sin K = 11 / 61

Taking the inverse sin of each side

sin ^-1 ( sin K) = sin ^-1 (11/61)

K =10.38885782

K = 10

A runner is participating in a 10.3 mile race. If the runner stopped at a water station that is twice as far from the starting l

Rudik [331]

We have the representation of this problem in the figure below. As we have a 10.3 mile race, then the equation is fulfilled as:

$d = 10.3mi = d_{1}+ d_{2}$

We know that there is a water station that is twice as far from the starting line as from the finish line, then:

 $d_{2}=2d_{1}$

So:

$d_{1} +2d_{1}=10.3$
∴ $d_{1}=3.43mi$

and $d_{2}=2(3.43)=6.86mi$

Finally, the distance of the runner from the finish line is:

$6.86mi$
