Answer 1

8,75xX+1,25xX=20

(8,75+1,25)xX=20

10          x    X=20

                    X=20:10

                    X=2

Chúc bn học tốt

Answer 2

87,5 * x + 1,25 *x = 20 

=> x*(87,5 + 1,25) = 20 

=> x * 88,75 = 20 

=> x = 20 : 88,75 = 16/71

Vậy x = 16/71 

Answer 3

\(87,5\cdot x+1,25\cdot x=20\)

\(=>x\cdot\left(87,5+1,25\right)=20\)

\(=>x\cdot88,75=20\)

\(=>x=\frac{16}{71}\)

Answer 4

\(8,75\cdot x+1,25\cdot x=20\)

\(=>x\cdot\left(8,75+1,25\right)=20\)

\(=>x\cdot10=20\)

\(=>x=2\)

Answer 5

87,5.x+1,25.x=20

(87,5+1,25).x=20

        88,75.x=20

                 x=20:88,75

                 x=0,2253522112

Answer 6

87.5 × x + 1.25 × x = 20

( 87.5 + 1.25 ) × x = 20

88.75 × x = 20

              x = 20 ÷ 88.75

              x = 0.22

Vậy, x = 0.22

Cbht

Answer 7

x.(87,5+1,25)=20

x.88,75=20

x=20:88,75

x=0,225....
