What makes the value n of the equation true -2n+1.8=3.2

Sonbull [250]

-2n + 1.8 = 3.2
Subtract 1.8 from both sides
-2n = 1.4
Divide both sides by -2
n = 1.4/-2 = 0.7/-1 = -0.7
n = -0.7

Check your work:
-2(-0.7) + 1.8 = 3.2
1.4 + 1.8 = 3.2
3.2 = 3.2

The answer is B. -0.7

Andrea has just created a scale drawing of her bedroom room which is 18 feet long by 12 feet wide. The scale drawing shows the l

dalvyx [7]

The width of scale drawing is 4 inches

Step-by-step explanation:

The length of room =L1= 18 ft

The width of room =W1= 12 ft

The scale drawing length=L2 = 6 inches

The scale drawing width W2= x

According to rule of three

$\frac{L1}{L2} = \frac{W1}{W2}$

putting values in equation we get

$\frac{18}{6} = \frac{12}{x}$

$3=\frac{12}{x}$

Re-arranging the equation we get

$x=\frac{12}{3} \\x= 4$

So the width of scale drawing is 4 inches
