Question

Hei , daca imi rezolvati asta ! VA DAU COROANA si dau multe puncte , cine comenteaza pentru puncte are raport!

Answer 1

h)6×5:10+h=296
3+h=296
h=296-3
h=293
i) [(124+692)-400×2]:i=4
(124+692-800):i=4
16:i=4
16supra i=4
16=4i
4i=16
i=4
j)(24:3+45:5)+143=4×j+124
(8+9)+143=4j+124
17+143=4j+124
160=4j+124
-4j=124-160
-4j= -36
j=9
k)12×2:k=4
12×2 supra k =4
24 supra k =4
24=4k
4k=24
k=6
l)(4×l+5)-6×2=5
4l+5-6×2=5
4l-12=0
4l=12
l=3
m)m:7+(123×3-53×4)=164
m supra 4+(369-212)=164
m supra 4+157=164
m=656-628
m=28
n)(n-45:9)×3=2185-2164
(n-5)×3=21
3n-15=21
3n=21+15
3n=36
n=12
o)(24-7×3)×5×2:o=30:10
(24-7×3)×5×2×10=30o
3×5×2×10=30o
300=30o
o=10
p)(p-28-7+200)×5=32 000+3×10
(p+165)×5=32000+30
5p+825=32030
5p=32030-825
5p=31205
p=6241
r)r×r+648=7×100+2×10+3×3
r2+648=700+20+9
r2+648=729
r2=729-648
r1=-9
r2=9
coroana? Am stat ceva la calcule!! Te rog am mare nevoie!
