2(x -9) = 9 divided ( - 1/3) what value of x makes the equation true <br> plsss help :)))
Ivanshal [37]

Answer:

x = -9/2

Step-by-step explanation:

1. Divide 9 by -1/3:

\frac{9}{1} ÷ -\frac{1}{3} = \frac{9}{1} · -\frac{3}{1}

= -27

2. Divide both sides by 2:

2(x - 9) = -27

\frac{2(x-9)}{2} = \frac{-27}{2}

(x - 9) = -\frac{27}{2}

3. Add 9 to both sides:

x = -\frac{9}{2}

(or 4.5 if you need it in decimal form)

hope this helps!

Simipified the exprestion -1.7+(-6.3).On the test when maureen simipified the exression she got -4.6. What mistake did maureen l
Rasek [7]

Answer:

Maureen ignored the negative(minus) sign in 1.7 thereby turning it into positive 1.7

Step-by-step explanation:

-1.7 + (-6.3)

Correct simplification

-1.7 + (-6.3)

Open parenthesis

= - 1.7 - 6.3

= -8

NOTE:

- * + = -

- * - = +

+ * - = -

+ * + = +

Maureen's simplification

-1.7 + (-6.3)

= 1.7 - 6.3

= -4.6

Maureen ignored the negative(minus) sign in 1.7 thereby turning it into positive 1.7
