2. (40:5+r):8=9:3=
3.40 m+16:8=9:3=
4.(s:5+16):8=9:3=
5.ax2x5:4=10
6.a:4+942:6-25:5)=8
Rezolvati va rog!

Answer 1

(40:5+16):a=9:3
(8+16):a=3

24:a=3
a=24:3
a=8

(40:5+r):8=9:3

(8+r):8=3
8+r=3x8
8+r=24
r=24-8
r=16


40 m+16:8=9:3

40 m+2=3
40m=3-2
40m=1
m=1/40


(s:5+16):8=9:3

(s:5+16):8=3

s:5+16=3x8
s:5+16=24
s:5=24-16
s:5=8
s=8x5
s=40




ax2x5:4=10

ax2x5=10x4
ax2x5=40

ax2=40:5
ax2=8
a=8:2
a=4



a:4+942:6-25:5=8

a:4+157-5=8
a:4+152=8
a:4=8-152
a:4=-144
a=-576

Answer 2

1. (8+16):a=3
24:a=3
a=24:3=8
2.   (8+r):8=3
8+r=3x8=24
r=24-8=16
3)40m+2=3
40m=3-2=1
m=1/40
4)(s:5+16):8=3
s:5+16=3x8=24
s:5=24-16=8
s=5x8=40
5)10a:4=10
10a=10x4=40
a=40/10=4
6)a:4+157-5=8
a:4=8+5-157=-144
a=-144x4=576
