Answer: -1

Step-by-step explanation:11 - 3(x+2) = 9+x

11 - 3x - 6 = 9 + x

11 - 6 - 3x = 9 + x

5 - 3x = 9 + x

-3x - x = 9 - 5

-4x = 4

x = 4 ÷ -4

x= -1

Using words, explain all steps of dimensional analysis when converting 6.7 hectometers to meters.
9966 [12]
<h2>6.7 hectometers is equal to "670 meters".</h2>

Step-by-step explanation:

We have,

6.7 hectometers

To convert 6.7 hectometers to meters.

We know that,

1 hectometer = 100 meters

⇒ 1 hm = 100 m

∴ 6.7 hectometers

= 6.7 × 100 meters

= 670 meters

∴ 6.7 hectometers (hm) = 670 meters (m)

Thus, 6.7 hectometers is equal to "670 meters".

Look at the system of equations below.
Paul [167]

Answer:

\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}

x=2,\:y=-1

Step-by-step explanation:

Considering the system of the equation

\begin{bmatrix}y=-2x+3\\ 4x-3y=11\end{bmatrix}

\mathrm{Subsititute\:}y=-2x+3

\begin{bmatrix}4x-3\left(-2x+3\right)=11\end{bmatrix}

\mathrm{Isolate}\:x\:\mathrm{for}\:4x-3\left(-2x+3\right)=11

4x-3\left(-2x+3\right)=11

4x+6x-9=11

10x-9=11

10x-9+9=11+9

10x=20

x=2

\mathrm{For\:}y=-2x+3

\mathrm{Subsititute\:}x=2

y=-2\cdot \:2+3

y=-1

\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}

x=2,\:y=-1
