Question

si x =25y y=2.2 entonces 2x-1/2y +2xy​

Answer 1

Explicación paso a paso:

2 (25) - 1/2 (2.2) + 2 (25) (2.2)

50 - 1,1 + 110

158,9

Answer 2

Explicación paso a paso:

Si X=25

2(25)-1/2(2.2) +2(25)(2.2)=

160 - 1/4.4=

704-44 / 4.4=

699.6 4.4=

159

Si X=25y

2(25y) -1/2(2.2) +2 (25y) (2.2)=

50y. - 1/4.4. + 110y =

160y. = - 1/4.4

Y = 160(1/4.4)

Y= 0.417

X=25y

X=25(0.417)

X=10.41
