5x + 23 = -2x - 12
First, you carry the variables to one side and the rational numbers to the other.
5x + 23 = -2x - 12
- 23 = +23
________________
5x = -2x + 11
+2x = +2x
________________
7x = 11
The you divide 11 by 7 to get x.
x = 1.571
Hope this helps!
Answer:
Sample A Estimate: 330
Sample B Estimate: 420
Sample C Estimate: 360
Median: 360
Range: 90
Step-by-step explanation:
For the sample estimate, multiply 600 by 11/20, 7/10, and 3/5 in order.
600 * 11/20
6600/20
330 people for Estimate A.
600 * 7/10
420/10
420 people for Estimate B.
600 * 3/5
1800/5
360 people for Estimate C.
330, 360, 420
360 is the median of these estimates.
420 - 330 = 90
90 is the range of these estimates.
W = 3 ( 2a + b ) - 4
w = 6a + 3b - 4
w + 4 - 3b = 6a
a = w + 4 - 3b / 6
