Question

Va rog sa ma ajutati!! Dau coronita !!!
1.Sa se afle x daca
,2x + 13,=(7,35) la puterea 2
6 *( x + 1,2) - 3,6
x + 12,5- 10,6= 40,01

2. Calculati media aritmetica a numerelor x,ysi z unde
x=( 12,1- 11,9) / 4+ 4,5
y=( 2,3 + 1,5) * 2,5
z= 11- (0,5 + 2,5)


/=impartire
*=inmultire

Answer 2

1.     2x+13=7,35²

2x+13=54,0225

2x=54,0225-13

2x=41,0225 | :2

x=20,51125



6•(x+1,2)=3,6 |:6

x+1,2=0,6

x=-0,6


x+12,5-10,6=40,01

x=40,01-12,5+10,6

x=38,11


2.   x=(12,1-11,9)/4+4,5=0,2/4+4,5=0,05+4,5=4,55

y=(2,3+1,5)*2,5= 3,8*2,5= 9,5

z=11-(0,5+2,5)=11-3=8


Ma=4,55+9,5+8 / 3=22,05/3=7,35
