s = c + 4
s = c + 4
s = 4c
s = 4 c
c = s + 4
c = s + 4
c = 4s
The equation that represents the pattern in the table is c = s + 4.

Question
Which equation matches the statement: “The sum of –4x and 2 is 9”?
(1 point)
Responses
–4x + 2 = 9
–4 x + 2 = 9
–4x + 9 = 2
–4 x + 9 = 2
–4x(2) = 9
–4 x (2) = 9
–4x – 2 = 9
–4 x – 2 = 9
The equation that matches the statement "The sum of -4x and 2 is 9" is -4x + 2 = 9.

Question
Solve. x – 6 = –18
(1 point)
Responses
x = –24
x = –24
x = –12
x = –12
x = 12
x = 12
x = 6
x = 6
To solve the equation x - 6 = -18, you can add 6 to both sides of the equation:
x - 6 + 6 = -18 + 6
This simplifies to:
x = -12
Therefore, the correct solution is x = -12.

Question
Solve. 4x + 3 = 47
(1 point)
Responses
x = 11
x = 11
x = 40
x = 40
x = 44
x = 44
x = 50
x = 50
To solve the equation 4x + 3 = 47, you can subtract 3 from both sides of the equation:
4x + 3 - 3 = 47 - 3
This simplifies to:
4x = 44
Then, divide both sides of the equation by 4:
x = 44/4
This simplifies to:
x = 11
Therefore, the correct solution is x = 11.
