Answer:

9+5=|2x+3|

14=|2x+3|

2 scenarios:

(1) 2x+3 >=0, equation is now 14=2x+3

11=2x

x=5.5

(2) 2x+3<0, equation is now 14=-(2x+3)

2x+3+14=0

2x=-17

x=-8.5

Answer:

x = 11/2 or -17/2.

Step-by-step explanation:

9 = |2x+3| -5

9 + 5 = |2x+3|

|2x + 3| = 14

2x + 3 = 14 or 2x + 3 = -14

x = 11/2 or -17/2.

Divide and simplify 4/7÷(-11/2)

lys-0071 [83]

Answer: $-\frac{8}{77}$

Step-by-step explanation:

$\frac{\frac{4}{7} }{-\frac{11}{2} }$

Multiply by the reciprocal in order to get rid of the fraction in the denominator.

$\frac{\frac{4}{7} }{-\frac{11}{2} }*-\frac{2}{11}$

$\frac{4}{7}*-\frac{2}{11}$

$-\frac{8}{77}$

Which of the following expressions are equivalent to -19/8 x(-50)

dmitriy555 [2]

1. Move the negative sign to the left.

- $\frac{19}{8}$ $X$ *-50

2. Use this rule: $\frac{a}{b}$ $*$ $\frac{c}{d}$ = $\frac{ac}{bd}$

- $\frac{19x*-50}{8}$

3. Simplify - $\frac{-950x}{8}$

4. Move the negative sign to the left.

-(-950x/8)

5. Simplify 950x/8 to 475x/4

6. Remove parentheses.
