Which of the following is a solution to the equation y = 3x - 1
A. (4,1)
B. (2, 5)
C. (4, 3)
D. (0, -3)
Give answers based on the choices listed
A. (4,1)
Which equation represents the pattern in the table below
Sal and Carrie’s ages
Sal 3, 5, 8, 13, 15
Carrie 7, 9, 12, 17, 19
A. S = c + 4
B. S = 4c
C. C = s + 4
D. C = 4s
A. S = c + 4
Which equation matches the statement “the sum of -4x and 2 is 9?”?
A. -4X + 2 = 9
B. -4x + 9 = 2
C. -4X(2) = 9
D. -4X - 2 = 9
A. -4X + 2 = 9
Solve. X - 6 = -18
A. X = -24
B. X = -12
C. X = 12
D. X = 6
Adding 6 to both sides of the equation:
X - 6 + 6 = -18 + 6
X = -12
Therefore, the correct answer is:
B. X = -12
Solve. 4x + 3 = 47
A. X = 11
B. X = 40
C. X = 44
D. X = 50
Subtracting 3 from both sides of the equation:
4x + 3 - 3 = 47 - 3
4x = 44
Dividing both sides of the equation by 4:
4x/4 = 44/4
x = 11
Therefore, the correct answer is:
A. x = 11
Solve 1/3 x = 12
A. X = 4
B. X = 15
C. X= 36
D. X = 39
