Find the value of x round to the nearest tenth

Mathematics
1 answer:
zzz [600]3 years ago
7 0

Answer:

  4.1 cm

Step-by-step explanation:

The segment marked x bisects the chord, so the triangle shown has legs x and 7.8, and hypotenuse 8.8.

The Pythagorean theorem can be used to find x:

  8.8² = x² +7.8²

  x² = 8.8² -7.8² = 77.44 -60.84 = 16.60

  x = √16.6

  x ≈ 4.1 . . . cm

Answer:

x=9

Step-by-step explanation:

step one pull out the factors

 3x - 27  =   3 • (x - 9)

and step two: Equations which are never true

2.1      Solve :    3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

so x-9=0 and add both sides to 9 and to equal 9

11 1/2 and 13 3/4 is?
Tpy6a [65]
This would depend on what you are asking for.

If you are adding the two numbers(which the word and is implying) you’re answer is 25 1/4.

You get this by finding a common denominator. In this case, that can be 4.

Turn 1/2 in to 2/4.

Next, you add 11 and 13 to get 24.

Then, you’ll add 2/4 and 3/4. You will get 1 1/4

Add 24 and 1 1/4. You have your answer of 25 1/4
