Answer:
9 boxes were packed. 10 brownies were left over.
Step-by-step explanation:
127 ÷ 13 = 9 R10
13 x 9 = 10 x 9 + 3 x 9 = 90 + 27 = 117
127 - 117 = 10
Answer: x=5√3(you've got it correct!)
y=15
In∆ADC,
Cos 60°=DC/10
DC=5
y=20-5
y=15
Standard form is ax + by = c
y + 2 = -3x + 3 [distributed the -3]
3x + y + 2 = 3 [added 3x to both sides]
3x + y = 1 [subtracted 2 from both sides]
3x + y = 1 should be your answer
Answer:
1) 36 sides
2) 170
