D=-1
-15d=15 so -d=1 so d=-1
How man bags were used?
41 / 3 = 13.7
We can say about 14 bags by rounding to the nearest whole number. Therefore, 14 bags were used.
5×3=15 (total circles)
15÷6 = 2.5 ( circles each students get )
6.2n-3.7n=85+45
2.5n=130
N=130/2.5
N=52
The answer is B. Hope this helps!
Answer:
1. y=mx+b
(5 , 5) (10 , 10)
5m+b=5 10m+b=10
10m+b-5m-b=5
5m=5
m=1
5+b=5
b=0
So for 1---10s the slope is: y = x
2. y=mx+b
(10 , 10) (35 , 10)
10m+b=10 35m+b=10
35m+b-10m-b=0
25m=0
m=0
b=10
So for 10-----35s the slope is: y=10
3. y=mx+b
(35 , 10) (0 , 0)
35m+b=10 b=0
35m=10
m=2/7
So for 35----40s the slope is: y= 2/7 x
