Answer:
marcia must have sold at least 22 chocolate cones.
Step-by-step explanation:
Jan sold a total of 65 cones (20+15+30). Tomas sold a total of 68 cones (20+18+30).
If Marcia sold more cones than Jan or Tomas, she had to have sold more than 68 cones in total. 30+17 = 47. I subtracted 68-47, to see how many chocolate cones she should have sold to match the number of cones Tomas sold, which is 21 chocolate cones. Therefore, to surpass Tomas in the total number of cones sold, she had to have sold at least 22 chocolate cones.
Answer:
The next 3 numbers to the given pattern of integers is -2,-1,-1,0,-1,1,-2 are 3,-5,8
Step-by-step explanation:
Given pattern of integers is -2,-1,-1,0,-1,1,-2
To find their next 3 numbers of the given pattern :
Let 




Therefore 



Therefore
Similarly we have
,
,
The general form to the given pattern is
for 
Therefore to find the
Put n=8 in 




Put n=9 in 




Put n=10 in 




Therefore the next 3 numbers are 3,-5,8

Answer:
x intercept is (45/2,0)
y intercept is (0,-36)
Step-by-step explanation:
Slope intercept form of equation of line is
y=mx+b where m is the slope and b is the y intercept
use any two points to find the slope
(10,20) (15,12)

m = -8/5
now we find out b using (10,20)

20 = -16 + b
add 16 on both sides , so b = 36
b is the y intercept , so y intercept is (0,-36)
Now we find x intercept
equation of line is y=mx+b that is 
To find x intercept plug in 0 for y

subtract 36 on both sides

Multiply by -5/8 on both sides


x intercept is (45/2,0)
Number 1 would the last option, but I’m not sure about number 2
