Answer:
0,-4
Step-by-step explanation:
I believe 3x-1 is the answer
Given data:
The given biology percentage is B=40%.
The given chemistry percentage is C=24%.
The percenage of earth science as compare to physics is E=P+4%.
The expresion for the sum of all subjects is,
B+C+E+P=100%
40%+24%+E+P=100%
E+P=36%.............................(I)
Substitute given value in the above expression.
P+4%+P=36%
2P=32%
P=16%
The nummber of students assigned earth science is,
E=16%+4%
=20%
Thus, the percentage of the students assigned to the physics subject is 16%.
Plug in 6 for everywhere s is in the equation
r = 9 + 3s
r = 9 + 3(6)
r = 9 + 18
r = 27
27 is the answer!
Step-by-step explanation:
100% - 25% off = 75%
Here, 75% of the initial price X, is the sale price of jeans during the season which is $60.
75/100 × X = $60
75X/100 =$60
( cross multiply)
75X=100×60
75X= 6000
X=6000÷75
X= $80
