Question

Afla valoarea lui ,,n'' din egalitatile:
5ori n plus 245 egal 845
54 impartit n plus 67ori 5 egal 344
n impartit 3 ori 8 egal 616
894 minus n impartit 4 egal 833
Repede sa fie corect si rezolvatile pe toate. Dau 30 pnct raspunsului corect.

Answer 1

$5*n+245=845$
$5*n=845-245$
$5*n=600$
$n= \frac{600}{5}$
$n=120$

$\frac{54}{n}+67*5=344$
$\frac{54}{n}+335=344$
$\frac{54}{n}=344-335$
$\frac{54}{n}=9$
$9n = 54$
$n=\frac{54}{9}=6$

$\frac{n}{3}*8=616$
$\frac{n}{3}= \frac{616}{8} =77$
$n=77*3$
$n=231$

$894-\frac{n}{4}=833$
$-\frac{n}{4}=833-894$
$-\frac{n}{4}=-61$
$\frac{n}{4}=61$
$n=61*4$
$n=244$

Answer 2

5xn+245=845
5xn=845-245
5n=600
n=600:5
n=120

54:n+67x5=344
54:n+335=344
54:n=344-335
54:n=9
n=54:9
n=6

n:3x8=616
n:3=616:8
n:3=77
n=77x3
n=231

894-n:4=833
n:4=894-833=61
n=61x4
n=244
