Answer:
Explanation:
Work out the equation:
1st row is 11 seat and the seat after it will be 6 more and 6 more after the second row and so on. This can be written:
6(x - 1) + 11 =
Where x determine the number of row.
Ex: if x = 1 thus, 6(0) + 11 = 11 seat which is the first row.
Find the number of seats in row 18:
6(18 - 1) + 11
6(17) + 11
= 102 + 11
= 113 seats
Answer:
6/3
Step-by-step explanation:
our average speed can be calculated in a couple different ways
is this case lets use a weighted average of the two speeds to find the average speed.
we know that that we were only going half as fast on the way back so it would take us twice as long
so our average speed would be (1/3) * 8 + (2/3) * 4
8/3 + 8/3 = 16/3 mph
another way to look at it is
to say we covered a total distance of 4 miles (2 out and 2 back)
the first 2 miles took us 1/4 of an hour since we were going at a rate of the 8 mph
the next 2 miles took us 1/2 of an hour since we were going at a rate of 4 mph
so we covered a distance of 4 miles in a time of 3/4 of an hour
distance = speed * time
speed = distance/time
speed = 4 /(3/4)
speed = 16/3 so either way we come up with the same answer
Answer:
6
Step-by-step explanation:
9 and 2/5 is the equivilent to 9 and 4/10
9 4/10 - 3 4/10 = 6 0/10
Should be 11.25 because 15 is 1/4 of 60 . U take 1/4 away from 60 so u gotta take 1/4 away from 15 which is 3.75 . And you get 11.25
The number beside the letter . for example 6x, 6 would be the variable
