Alexandria has been playing at the beach with 329 shells. She is putting shells into rows of 6. How many rows will she need if s
1 answer:
Answer:
Alexandria requires 55 rows to use all the shells.
Step-by-step explanation:
Given:
Number of Shells = 329
Number of shells in each row = 6
We need to find the number of rows she need if she wants to use all the shells.
Solution:
Now we know that;
number of rows she needs can be calculated by Dividing Number of Shells with Number of shells in each row.
framing in equation form we get;
number of rows =
Hence Alexandria requires 55 rows to use all the shells.

Answer:
use f(x)=y=mx+b
let snow = S, time = t instead of y and x
S(t)=mt+b
The rate of inches per hour represents the slope of the graph, m.
The y-variable would be the amount of snow, S.
The x-variable would be the time, t, in hours.
The function has three pieces:
i) S(t)= 2t (slope = 2)
ii) S(t) = 3t (slope = 3)
iii) S(t) = 0.75t (slope = 0.75)
For the first piece, i), t=3, so the amount of snow is 6 inches.
For the second piece, ii) t=5, so the amount of snow is 15 inches.
For the third piece, iii) t=1, so the amount of snow is 0.75 inch.
In total, it snowed 21.75 inches.
