C = 2 × pi × r
C= 2 × pi × 2.5
Your answer is
C = 5 × pi
7h + 6b = 35.50
5h + 6b = 30.50
The difference between the 2 totals spent is $5, and there were the same number of burgers, but 2 fewer hotdogs. So $5/2 = $2.50, the cost of a hot dog. Substitute that into the equations to solve for burgers (b)
5(2.50) + 6b = 30.50
12.50 + 6b = 30.50
6b = 18
b = 3
Check the work:
7(2.50) + 6(3) =
17.50 + 18 = 35.50
Answer:
C - 13
Step-by-step explanation:
2y+4=2(y+2)
2y+4=2y+4
4=4
so the answer is all real numbers or infinite solutions
11+5=16 3x2= 6 8x1= 8 so add it together, 16 + 6 + 8 = 30.
