Question

720 : ( a *2 + a*3) =2*3

Answer 1

Ta có \(720\div\left(a\times2+a\times3\right)=2\times3\)

\(\Rightarrow720\div\left(5\times a\right)=6\)

\(\Rightarrow5\times a=720\div6\)

\(\Rightarrow5\times a=120\)

\(\Rightarrow a=120\div5\)

\(\Rightarrow a=24\)

Answer 2

720:(a*2+a*3)=6

a*2+a*3=720:6

a*2+a*3=120

a*5=120

a=120:5

a=24

Answer 3

a=24

tk mk nha,cảm ơn nhiều ạ

Answer 4

720:(a*2+a*3)=2*3

720(a*(2+3))=6

a*(2+3)=720:6

a*5=120

a=120:5

a=24

Answer 5

720 : ( a x 2 + a x 3) = 2 x3

720 : (a x <2+3>) = 6

a x 6 = 720 : 6

=> a = 720

Answer 6

720 : ( a x 2 + a x 3 ) = 2 x 3

720 : [ a x ( 2 + 3 ) ] = 6

a x 5 = 720 : 6

a x 5 = 120

a = 120 : 5

a = 24

Answer 7

Trả lời :

720 : ( a x 2 + a x 3 ) = 2 x 3

=> 720 : ( a x 5 ) = 6

=> a x 5 = 720 : 6

=> a x 5 = 120

=> a = 120 : 5

a = 24

Vậy a = 24
