Answer:
(3x-1) + (3x-1) + (2x+1) = 55
Step-by-step explanation:
1. 3x + 3x + 2x = 8x
2. -1 + -1 + 1 = -1
3. 8x -1 = 55
4. 8x = 55 + 1
5. 8x = 56/8
6. x = 7
Answer:
See attached graph.
Step-by-step explanation:
To graph the line, convert the standard form into slope intercept form.
-x + 2y = 11
2y= x+11
y = 1/2 x + 11/2
Graph the equation by plotting the y-intercept (0,11/2) since b= 11/2.
Then from this point move up 1 unit and to the right 2 units. This point is (2, 13/2).
From this point move up 1 unit again and over to the right 2 units. This points is (4, 15/2).
Connect the points to the form the line.
Answer:
84 + 52=n+5: n = 131
47+16=49+n: n = 14
182-n=185-107: n - 107
79+14=77+n: n = 16
