Answer:
Step-by-step explanation:
Elvin and Carol together have Rs. 84. If Elvin gives Carol Rs. 32, then Carol will have twice as much money as Elvin. How much money, do Elvin and Carol have originally?
Let the amount of Elvin has originally = E
Let the amount of money Carol has originally be = C
E + C= Rs. 84
E + C = 84 ......Equation 1
If Elvin gives Carol Rs. 32, then Carol will have twice as much money as Elvin.
C + 32 = 2E
C = 2E - 32
We substitute into Equation 1
E + C = 84 ......Equation 1
E + 2E - 32 = 84
3E = 84 + 32
3E = 116
E = 116/3
E =

basically I learned this trick at school, you take the percent, in this case it’s 95/100 and then you write it next to the fraction of what your unit is, so x/20 students
then you multiply 95 and 20 then divide by 100.
Answer:
1/100 (1471 z + 2100)
0.01 (1471 z + 2100) the result I got
and the Factorization over the splitting field:
14.71 z + 21
Answer:
