Answer:
New mean=71.32
Step-by-step explanation:
The expression for the total initial score is;
T=M×S
where;
T=total initial score
M=mean score
S=number in the set
replacing;
T=unknown
M=72
S=17
replacing;
T=72×17=1,224
The total initial score=1,224
Determine the total score by;
total score=total initial score+total final score
where;
total initial score=1,224
total final score=(68+63)=131
replacing;
total score=1,224+131=1,355
Determine the new mean;
New mean=total score/new number
where;
total score=1,355
new number=(17+2)=19
replacing;
new mean=1,355/19=71.32
Answer:
x = 1/2 or 0.5
Step-by-step explanation:
Subtract 2 from both sides of the equation
x + 2 - 2 = 5x -2
Simplify
x = 5x -2
Subtract 5x from both sides of the equation
x = 5x -2
x - 5x = 5x - 2 - 5x
Solution
x = 1/2

Since 25% is 1/4, you multiply 60 by 1/4 to get how many students took Spanish class last year. So, 60 times 1/4 is 60/4, which is 15. Then you subtract 15 from 60 to get 45. So, 45 students took Spanish class last year.
