Step-by-step explanation:
<u>Step 1: Define Equation</u>
2(x + 4) = 4x + 3 - 2x + 5
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 2: 2x + 8 = 4x + 3 - 2x + 5
- Combine like terms: 2x + 8 = 2x + 8
- Subtract 8 on both sides: 2x = 2x
- Divide 2 on both sides: x = x
Here we see that <em>x</em> does indeed equal <em>x</em>.
∴ x = infinite amount of solutions
To find x:
use the formula: cos° = adajcent/hypo
cos 37° = x/ 16
answer: 12.8
The other length:
use the same formula
cos 57° = y/16
answer: 8.7

I see that 12 tickets is 4 times the 3 movie tickets.
So how much they pay for 12 tickets will also be 4 times the old amount of $15.75.
4*$15.75 = $63
You could also find how much one movie ticket is, then multiply the cost of one ticket by 12.
The cost of one ticket would be $15.75 / 3 = $5.25
Then 12 tickets would be 12($15.25) = $63
