Answer:

22

Step-by-step explanation:

(3x - 4)° + (3x - 17)° + 69° = 180°

6x - 21 + 69 = 180

6x + 48 = 180 ⇒ x = 22

Answer:

x = 22°

Step-by-step explanation:

The angles of a triangle add to 180°, so:

69 + (3x - 4) + (3x - 17) = 180

(3x - 4) + (3x - 17) = 111

6x - 21 = 111

6x = 132

x = 22

Which equations may be used to determine the 3 consecutive integers whose sum is 127?

s344n2d4d5 [400]

Answer:

a and b.

Step-by-step explanation:

I’ll explain by giving an example.

Let’s say that: a=3;b=4;c=5; => they all are consecutive -> their sum is 12.

=> if we use a) n=3 => 3*n+3=3*3+3=12 => correct.

b) n+(n+1)+(n+2)= 3+4+5=12=> correct.

c)n+2n+3n=3+6+9=18=>incorrect.

d)3n=3*3=9=>incorrect.

the performing arts department put in its spring show on Friday and Saturday nights. the price of a ticket was the same both nig

Galina-37 [17]

Let $p=$ the price of a ticket
Let $c=$ the cost to put on the show

Formula:
(profit) = (ticket price) * (number of people) - (cost to put on show)
We have two equations here:
$500=120p-c$
$400=100p-c$
Solve:
$100=20p$
⇒ $p=5$
⇒ $400=100(5)-c$
⇒ $400=500-c$
⇒ $c=100$

So the price of a ticket is $5, and the cost to put on the show is $100.
