Question

[(1,5^2+x)×0,2]:0,1=10

Answer 1

[ ( 1, 5 ^ 2 + x ) × 0, 2 ] : 0, 1 = 10

[ ( 2, 25 + x ) × 0, 2 ] : 0, 1 = 10

( 2, 25 + x ) × 0, 2 = 10 × 0, 1

( 2, 25 + x ) × 0 , 2 = 1

2, 25 + x = 1 : 0, 2

2, 25 + x = 5

x = 5 - 2, 25

x = 2, 75

Answer 2

Răspuns:

Explicație pas cu pas:

[(1,5^2+x)×0,2]:0,1=10

[(1,5^2+x)×0,2] = 10*0,1 = 1

(1,5^2+x) = 1 : 0,2 = 5

2,25 + x = 5

x = 5 - 2,25 = 2,75
