Answer:

47

Step-by-step explanation:

(2x + 3) + (5x - 8) = 72

2x + 3 + 5x - 8 = 72

(2 + 5)x + (3 - 8) = 72

7x - 5 = 72

7x = 72 + 5 = 77

x = 77/7 = 11

BC = 5x - 8 = 5 (11) - 8 = 55 - 8 = 47

To check solution: AB = 2x + 3 = 25, and AB + BC = AC = 72, so 25 + 47 = 72 verifies answer

Lines g and h are parallel and m 2 = 110°. what is m <6 A 6° B 70° C 110° D 180°
Ymorist [56]

Answer:

m<6 =110°

Step-by-step explanation:

We are given that

line g and h are parallel lines

And whenever two lines are parallel

then it's corresponding angles must be equal

We have corresponding angles as

<1 , <5 ; <2 , <6

so,

<2=<6

now, we are given

<2=110°

so, we get

<2=<6=110°

so, answer is

m<6 =110°

Given u=(5,-2,3) and v=(1,1,2) find ordered triple that represents 3u-2v
kipiarov [429]

Answer:

(13, -8, 5)

Step-by-step explanation:

Given

u = (5,-2,3)\\and\\v = (1,1,2)

We have to find 3u-2v

So,

3u = 3(5,-2,3)\\3u= (15,-6,9)\\\\And\\\\2v= 2(1,1,2)\\2v= (2,2,4)\\\\3u-2v = (15,-6,9) - (2,2,4)\\= (15-2, -6-2 , 9-4)\\= (13, -8, 5)

The ordered triple that represents 3u-2v is:

(13, -8, 5) ..

Which complex number has a distance of 17 from the origin on the complex plane?
Virty [35]

Answer:

None of the options are correct.

Step-by-step explanation:

Let the complex number is a + ib

Given distance from origin = 17 units

Now, by distance formula distance of a point  from the origin  =

17 = \sqrt{(x)^{2}  + (y)^{2} }

1) <u>Check for 2 + 15 i</u>

here, \sqrt{15^2  +  2^2}  = \sqrt{225 + 4} = \sqrt{229} ≠ 17

2)<u> Check for 17 +  i</u>

here, \sqrt{17^2  +  1^2}  = \sqrt{289 + 1} = \sqrt{290}≠ 17

3)<u> Check for 20 - 3 i</u>

here, \sqrt{20^2  +  (-3)^2}  = \sqrt{400 + 9} = \sqrt{409}≠ 17

4) <u>Check for 4 -  i</u>

here, \sqrt{4^2  +  (-1)^2}  = \sqrt{16 + 1} = \sqrt{17} ≠ 17

Hence,  none of the options are correct.

Explain how the statement "there is 3/4 cup per serving" represents a rate.
Aleonysh [2.5K]
There is 3/4 cup of whatever in one serving. If that serving amount changed to 2, then the 3/4 would be multiplied by 2. If there is half a serving, then it would be divided by 2. There is a constant change, and not one that is always changing.
