Answer:
(x, y) = (-1.4, 1.6)
Step-by-step explanation:
The graph shows the solution pretty clearly. It seems no estimation is required.
(3+1)/(0+3)= 4/3
the answer to the question is 4/3
Answer:
48y
Step-by-step explanation:
Use the distributive property:
31y +17y = (31 +17)y = 48y
Answer:
His mistake was he didn't multiply 3(4) when he was opening the parenthesis
Step-by-step explanation:
Correct solution:
12x – 5 = 3(x + 4)
Open parenthesis
12x – 5 = 3x + 12
Collect like terms
12x - 3x = 12 + 5
9x = 17
x = 17/9
x = 9 8/9
Incorrect solution:
12x – 5 = 3(x + 4)
His mistake was he didn't multiply 3(4) when he was opening the parenthesis
12x – 5 = 3x + 4
12x = 3x - 1
9x = -1
