your answer is 495 dollars. as 45 times 11 equals 495 being the 45 is students and 11 is price
; a₁ is the first term, d is the difference between terms, and n is the term
-4, -21, -38, ... ⇒ a₁ = -4, d = -17
= -4 - 17n + 17
= 13 - 17n
= 13 - 1088
= 1075

Answer:
The algebraic equation describing the above
X+y= x-30
Step-by-step explanation:
The initial temperature of the environment= x degrees
Temperature of the front= y degrees
the environment dropped 30 degrees, means loosed 30 degrees.
The final temperature f the environment= x-30
The algebraic equation describing the above
X+y= x-30
Answer:
13 2/9
Step-by-step explanation:
Cows eats=5 3/5 Hays everyday
Horses eats=1 5/6 as much as the cow
=1 5/6 of what the cow eat+5 3/5
=1 5/6 × 5 3/5 + 5 3/5
=11/6×28/6+28/6
= 308/36+28/6
=308+168/36
=476/36
=13 8/36
=13 2/9
