ohaa [14]
You would do an arithmetic sequence
use A1 +(n-1)d to calculate number of seats in the last row

An = 4+(24-1)5
An = 4 + (23)(5)
An = 4 + 115
An = 119 seats in the last row

now use a sum sequence to find total number of seats

Sn = n(a1 + an)/2 
Sn = 24(4+119)/2 
Sn = 24(123) /2 
Sn = 1476 total seats

Evaluate the following expression when x = -5 and y = 25.
kykrilka [37]

Answer:

<u>The correct answer is A. 3,120.</u>

Step-by-step explanation:

Let's solve the expression for x = -5 and y = 25, this way:

(5|x| - y³)/x

Replacing x and y, we have:

(5 * 5 - 25³)/-5 (Absolute value of -5 is 5 in the numerator but we keep it without changes in the denominator)

(25 - 15,625)/-5

-15,600/-5

3,120

<u>The correct answer is A. 3,120.</u>

Helen [10]
Sum means add
sum of the 3 is
n+n+1+n+2

it add to 57
n+n+1+n+2=57
3n+3=57
minus 3 both sides
3n=54
divide both sides by 3
n=15
n+1=16
n+2=17

the integers are 15,16, and 17
