Find "?"

Mathematics
1 answer:
USPshnik [31]3 years ago
4 0

Answer:

p = - 11x

q = - 6y + 3

r = 3z

s = - 15x + y

t = 2x - 14z - 11

u = 9y + 3x - 14

Step-by-step explanation:

Let, 7x + p + 3 - 9 = - 4x - 6

⇒ p = - 4x - 6 - 7x + 9 - 3

⇒ p = - 11x (Answer)

Let, - 19y  + q + 15 = - 25y + 18

⇒ q = - 25y + 19y + 18 - 15  

⇒ q = - 6y + 3 (Answer)

Let, - 7z + r - z + 14 = - 5z + 14

⇒ r = - 5z + 7z + z = 3z (Answer)

Let, 4x - 11y + s = - 11x - 10y

⇒ s = - 11x - 4x - 10y + 11y

⇒ s = - 15x + y (Answer)

Let, - 25x + z + t = - 23x - 13z - 11

⇒ t = - 23x + 25x - 13z - z - 11

⇒ t = 2x - 14z - 11 (Answer)

Let, 7y + u - 18 = 16y + 3x - 32

⇒ u = 16y - 7y + 3x - 32 + 18

⇒ u = 9y + 3x - 14 (Answer)

Three-fourths of the tickets had been sold, and there were 420 tickets left. How many tickets were printed?
BabaBlast [244]

Answer: 560 tickets

Step-by-step explanation:

3/4 = 420/x; now cross multiply:

3x = 4(420)

3x = 1,680; now divide both sides by 3, and you get x = 560

Which of these numbers is between 5/6 and 1?<br> (A) 4/5 <br> (B) 4/7 <br> (C)6/7
djverab [1.8K]
Two basic ways in which to do this problem:

1.  Find and apply the LCD.

2.  Convert all of the given numbers to their decimal form, to 2 or 3 places only.

Try #2 first:

5/6 = 0.83    

4/5 = 0.80 is not between 5/6 and 1.  Reject it.
4/7 = 0.57 Reject
6/7 = 0.86 This is between 5/6 and1.  This is the answer.

Which equation is a point slope form equation for line AB ?
Jobisdone [24]

For this case we have that by definition, the equation of a line of the point-slope form is given by:

y-y_ {0} = m (x-x_ {0})

Where:

m: It's the slope

(x_ {0}, y_ {0}):It is a point through which the line passes

To find the slope, we need two points through which the line passes, observing the image we have:

(x_ {1}, y_ {1}): (1,6)\\(x_ {2}, y_ {2}): (5, -2)\\m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {-2-6} {5-1} = \frac {-8} {4} = -2

Thus, the equation is of the form:

y-y_ {0} = - 2 (x-x_ {0})

We choose a point:

(x_{0}, y_ {0}) :( 5, -2)

Finally, the equation is:

y - (- 2) = - 2 (x-5)\\y + 2 = -2 (x-5)

Answer:

y + 2 = -2 (x-5)
