Question

Vă rog am nevoie la ex 2 b 3 ,5 , !!!!!!

Answer 1

3.a) $\frac{5656}{3232} = \frac{7}{4} (Decimal: 1.75)$
$\frac{565656}{323232} = \frac{7}{4} (Decimal: 1.75)$
SUNT EGALE
b) [tex] \frac{11}{35} \ \textless \ \frac{N}{35} \ \textless \ \frac{19}{35} [/tex]
$\frac{11}{35} \ \textless \ \frac{1}{35}N \ \textless \ \frac{19}{35}$ (Simplificarea tuturor inegalității)
[tex] \frac{11}{35} SUPRA \frac{1}{35} \ \textless \ \frac{1}{35}N SUPRA \frac{1}{35}\ \textless \ \frac{19}{35}SUPRA \frac{1}{35} [/tex] (Se împarte fiecare parte \ {1} / {35} \,)
11<N<19

Din păcate, am avut o problemă calcul a datelor introduse.

5.a) $2\frac{5}{6} = \frac{x}{12}$
$\frac{17}{6} = \frac{1}{12}x$
$\frac{1}{12}x= \frac{17}{6}$
$12*( \frac{1}{12}x)=12*( \frac{17}{6})$
x=34

b) $3* \frac{x}{x+1} = \frac{19}{5}$
$\frac{3x}{x+1} = \frac{19}{5}$
3x*(5)=19*(x+1)
15x=19x+19
15x−19x=19x+19−19x−4x=19
$\frac{-4x}{-4} = \frac{19}{-4}$
$x= \frac{19}{-4}$
