Answer:

The value of the expression at x=5 is 10

Set them equal to each other and solve
3x + 39 = 4x +34
-x=-5
X=5
Plug it in
3(5) + 39 = 54
4(5) +34 = 54
For the final angle ,
54 + 54 = 108
180-108 =72
The angle measures are 54,54, and 72

max2010maxim [7]

Answer:

x = 5.625

Step-by-step explanation:

<u>Step 1:  Make an expression</u>

<u />\frac{3}{4} = \frac{x}{7.5}

<u>Step 2:  Cross Multiply</u>

<u />\frac{3}{4} = \frac{x}{7.5}

4 * x = 7.5 * 3

4x = 22.5

<u>Step 3:  Divide both sides by 4</u>

<u />4x / 4 = 22.5 / 4

x = 5.625

Answer:  x = 5.625

PSYCHO15rus [73]

Answer:

the number of adult ticket sold is 107 tickets

The computation of the number of adult ticket sold is shown below:

Let us assume the number of tickets be x,

So, the adult be x

And for student it would be 3x

Students= 2x

Adults= x

Total = 4x

Now the equation could be

4x = 428

x = 107

This x signifies the adult tickets sold i.e 107

Hence, the number of adult ticket sold is 107 tickets
