2x + 7= -11 please help
Dvinal [7]

Answer:

x = -9

Step-by-step explanation:

You are solving for x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 7 from both sides:

2x + 7 (-7) = -11 (-7)

2x = -11 - 7

2x = -18

Next, divide 2 from both sides:

(2x)/2 = (-18)/2

x = -18/2

x = -9

x = -9 is your answer.

Express 19.79 as a mixed number.
sergey [27]
Write the decimal number as a fraction
(over 1)
19.79 = 19.79 / 1

Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's

Numerator = 19.79 × 10 × 10 = 1979

Denominator  = 1 × 10 × 10 = 100

Numerator / Denominator = 1979 / 100

Simplifying our fraction

= 1979/100

= 1979/100

= 19  79/100
