Answer:
x = 10
Step-by-step explanation:
9x + 9 = 8x + 19
9x - 8x = 19 -9
x =10
The answer is in slope form : Y=1x+5
Reason: all you do is (rise/run) to get the slope. So take (5/5)=1x (slope). Also, your intercept is +5.
We have the given in the problem as mentioned:
A total of 130 students and only 7 had been placed in the wrong math class.
With this given, we can easily draw the proportion of all students who have been placed in the wrong math class by estimation method and the solution is shown below:
Proportion = 7/130
