2a+1b=27.50
4a+2b=59.50
Multiply first equation by -4 and the second by 2 so you can drop off the a values then add the equations together. Then solve for b. You should get b=6.
Then plug b into one of the original equations and solve for a and you should get 10.75
So a plate of spaghetti is $10.75 and a salad is $6.

If wrong i apologize but for that equation i got the answer K=117
Answer:
g = 7 yards
Step-by-step explanation:
you have 7
yards for the angle adjacent 30 deg.
tan 60 =
tan 60 = 7
/ g
7 * root(3) / g = root(3)
7/g = 1
g = 7 yards

X² + 12x = 40
x² + 12x + (6)² = 40 + (6)²
x² + 12x + 36 = 40 + 36
(x + 6)² = 76
Answer: 36 must be added to both sides to complete the square.
