Answer:
Step-by-step explanation:
Angles <em>B</em><em> </em>and<em> </em><em>C</em><em> </em>form a straight angle, so you set both expressions equal to 180°:
180° = (2x + 15)° + x°
180° = 15° + [3x]°
- 15° - 15°
____________
![\displaystyle \frac{165°}{3°} = \frac{[3x]°}{3°} \\ \\ 55° = x](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B165%C2%B0%7D%7B3%C2%B0%7D%20%3D%20%5Cfrac%7B%5B3x%5D%C2%B0%7D%7B3%C2%B0%7D%20%5C%5C%20%5C%5C%2055%C2%B0%20%3D%20x)

Answer:
hotdog $1, and hamburger $2
Step-by-step explanation:
D-is hot dogs, H-hamburgers
7D +4H = 15
4D +7H = 18
we got 2 equations with 2 unknown so we can solve
7D +4H = 15 multiply by 7
4D +7H = 18 multiply by -4
49D +28H = 105
-16D -28H = -72 add the two equations
33D= 33 so D=$1
go back to the first equation:
7*1 +4H =15 gives us 4H = 15-7; 4H = 8 so H= $2
