Explicație pas cu pas:
Fie numărul = x
x + 4 = e - - (1)
e * 4 = f - - - (2)
Ecuația 2 - 4 împărțită la 4 = 4
(f - 4) / 4 = 4
Crucea se înmulțește
f - 4 = 16
f = 16 + 4
f = 20
Rezultatul 1 împărțit la 4 este egal cu 4
Prin urmare,
e = f / 4
f = 20
e = 20/4
e = 5
De la (1)
x + 4 = e
x + 4 = 5
x = 5 - 4
x = 1
Answer:
<h2>3919832.65306</h2>
Step-by-step explanation:
This problem is focused on percentages.
Now given that 49% of a number is 1,920,718
we can say let the number be x
so 49% of x= 1,920,718
now expressing this problem mathematically we have
(49/100)*x= 1,920,718
0.49x= 1,920,718
divide both sides by 0.49 we have
x= 1,920,718/0.49
x= 3919832.65306
Therefore the total that were granted degree that year was 3919832.65306
