Create formulas!

x=number of adult tickets

y=number of student tickets

x+y=644  <em>total sold</em>

56+y=x    <em>student was 56 less than adult</em>

Perform substitution

(56+y)+y=644

56+2y=644

2y=588

y=294

Substitute y into the formula we created

x+294=644

x=350

350 adult tickets were sold.

Answer:

Step-by-step explanation:

Let x be the number of adult tickets.

Number of student tickets = 56 fewer than adult tickets

                                            = x - 56

Total tickets  = 644

x + (x - 56) = 644

x + x - 56 = 644

2x - 56 = 644

Add 56 to both sides

2x - 56 + 56 = 644 + 56

2x = 700

Divide both sides by 2

2x/2 = 700/2

x = 350

350 adult tickets were sold

The measures of two angles in a triangle are 32o and 78o. Which of the following equations could be used to find the measure of
Korvikt [17]

Answer:

32+78+x=180

Step-by-step explanation:

All triangle angles add up to 180, so add 78 and 32 then subtract it from 180 to get x, which in another form is 32+78+x=180.

seraphim [82]

Answer:

a + b + c = \pi \\  =  > c=  \pi - a - b \\  <  =  >  \tan(c)  =  \tan(\pi - a - b)  =  -\tan(a + b)

Step-by-step explanation:

we have:

\tan(a)  +  \tan(b)  +  \tan(c)  \\  =  \tan(a)  +  \tan(b)  -  \tan(a + b)  \\  =  \tan( a)  +  \tan(b)  -  \frac{ \tan(a) +  \tan(b)  }{1 -  \tan(a)  \tan(b) }  \\  =  \frac{ ( \tan(a) +  \tan(b)  ) \tan(a) \tan(b)  }{ \tan(a) \tan(b)  - 1 } (1)

we also have:

\tan(a)  \tan(b)  \tan(c)  \\  =  -  \tan(a)  \tan(b)  \tan(a + b)  \\  =  \frac{ -(\tan( a  )   + \tan(b) ) \tan(a)  \tan(b) }{1 -  \tan(a)  \tan(b) }  \\  =  \frac{( \tan(a)  +  \tan(b)) \tan(a)   \tan(b) }{ \tan(a) \tan(b)  - 1 } (2)

from (1)(2) => proven

gavmur [86]

Answer:

The reviewers can determine the experiment's feasibility.

Step-by-step explanation:

First of all this isn't math but the answer is between A & B, typically it is checked for mistakes that could lead to it being flawed. From this It is most likely A due to it being a paper and not an actual experiment, they would be looking for if it COULD happen, not if it WILL happen. They wouldn't add their own findings to someone elses paper, and it typically isn't for funding.
