Initial number of students: 220
Final number of students : 180
Multiply the initial number of students (220) by the percentage change in decimal form (divided by 100) - That expression must be equal to 180.
220 x = 180
Solve for x:
x=180/220
x= 0.818181
multiply by 100
81,81 %
100%-81,81% = 18.18%
Percent change: 18.18%
Answer: slope = 1
Step-by-step explanation:
For two lines to be parallel then they have the same slope , if the slope of line 1 is M1 and then slope of line 2 is M2 , if they are parallel then M1 = M2.
Given; y- 4 = + (x + 8)
Make y the subject of the formula , so that the equation can be in slope - intercept form , that is in the form y = mx + c , where m is the slope and c is the y - intercept.
y - 4 = x + 8
Add 4 to both sides
y = x + 8 +4
y = x + 12
since the coefficient of x is 1 , this means that the slope is 1 , any line that will be parallel to this line must have a slope which is 1
Answer:
900
Step-by-step explanation:
Because the unit rate of mins per mile is 7.5 min for each mile. So, then you multiply 120 with 7.5 and move the decimal place to get
