. If m angle TUV = (9x + 1)° , m angle TUW = (7x – 9)°, and m angle WUV = (5x - 11)°, find the value of x.​
Fed [463]
Answer:

x = 7

Step-by-step explanation:

Suppose ray UW divides ∠TUV into two angles ∠ TUW and ∠ WUV.

Then, m∠TUV = m∠ TUW + m ∠ WUV

Given m∠TUV = (9x + 1), m∠ TUW = (7x - 9) and m ∠ WUV = (5x - 11)

Substitute these values in (i) we get

9x + 1 = 7x - 9 + 5x - 11
9x + 1 = 7x + 5x - 9 - 11
9x + 1 = 12x - 20
12x - 9x = 1 + 20
3x = 21
x = 21/3
x = 7

If there is a positive correlation between number of years studying math and shoe size ​(for children), does that prove that lar
stealth61 [152]

Answer:

The hidden variable is age.

Step-by-step explanation:

That does not prove that  larger shoes cause more studying math or vice versa.

The children with larger shoes are most probably older  so they would have done  more years of studying than the younger ones.

The hidden variable is the age of the child.

One of Marianna's homework problems was to solve the equation below.
Strike441 [17]

Answer:

<h2>Marianna is incorrect because x2</h2><h2>2x13 can be factored into two binomials</h2>

Step-by-step explanation:

ax^2+bx+c = 0

x=−1+√14 or x=−1−√14

discriminant=56

completing square x=−1+√14 or x=−1−√14

Now, we can solve each term for  

x=-2 she is incorrect

x(x+2)=0

Now, we can solve each term for  

0:  

x=0

- no other work needed,

and

x+2=0

x+2-2=0-2

x+0=-2

<u>x=-2</u>
