If he used half as many hot dog buns, he used 6 bags of <span>hot dog buns on Thursday. </span>
I got A, -32, but it has been awhile since I have learned this in my math class. You might want to wait for someone else to verify this answer.
Scale : 1 cm = 2.5 ft
1 cm = 2.5 ft
0.5 cm = 2.5 x 0.5 = 1.25 ft
Circumference = πD = π(1.25) = 3.93 ft
Answer: 3.93 ft
-3(k+7)-5k+4=23
-3k-21-5k+4=23
Get rid of the numbers that aren't being multiplied by k:
-3k-5k=23+21-4
Add like things:
-8k=40
Divide by -8 on both sides to get k by itself and to make the equation even:
k=-5
I think its B. Because 396 divided by 3 equals 132 (there's 3 feet in a yard)
