Answer:
The sum of the first five classroom numbers in a row is 5k + 20
Step-by-step explanation:
Since the smallest classroom number on the side of the building is numbered k and each consecutive odd integer is separated by a difference of
2.
Therefore:
k is the first class room.
k + 2 is the second class room.
k + 4 is the third class room.
k + 6 is the third class room.
k + 8 is the fifth class room.
The sum of the five consecutive class rooms are given as:
k + (k + 2) + (k + 4) + (k + 6) + (k + 8)
collecting alike terms we get
= k + k + k + k + k + 2 + 4 + 6 + 8
= 5k + 20
Therefore, The sum of the first five classroom numbers in a row is 5k + 20.
2x + 3y = 36
2x + 3*6 = 36
2x + 18 = 36
-18 -18
___________
2x = 18
/2 /2
___________
x = 9
Oh I’m not sure what your talking about
Answer:

b is 77
Step-by-step explanation:
Give me brainllest
It's B for the total is 23.24 so the equation equals that , since Joseph buys 7 of each packet its 7 tomato packets which is 7t and 7 cucumber packets , since we know the price for each cucumber packet we can do 7 times 1.89. The total cost of the packets equal 23.24 so we do 7(1.89) +7t = 23.24
