−1/2x − 1/5 − 5x + 3/10 + 3/2x

Answers

Answer 1

Answer:

-4x+1/10

Step-by-step explanation:

−1/2x−1/5−5x+3/10+3/2x

Combine like terms

-5x−1/2x+3/2x+3/10 - 1/5

Taking parts

-5x -1/2x + 3/2x = -5x +2/2x =-4x

3/10 -1/5  and getting a common denominator

3/10 -1/5*2/2= 3/10-2/10 = 1/10

Putting it back together

-4x +1/10

There is not enough information to solve for x.

And the angle measures are probably 90 degrees if the transversal (the line cutting through the two parallel lines) is perpendicular to the parallel lines

The area of a rectangle is 294.4 sq.cm. The length of one side is 16cm. What is the perimeter?
Area = L x w
Perimeter = L + L + W + W

Answers

the perimeter is 68.8cm

Ok so because this is a rectangle the line directly across (paralell) is equal, so if one line is 16cm, the line parallel to that will also be 16. Then the formula for area is LxW we'd plug in the numbers we know to get 294.4[tex]cm^{2}[/tex] =16 x W

then we divide 16 by both sides to make it even to get 18.4cm=W. Now we just plug everything in to the perimeter by doing 16 x 2 + 18.4 x 2 to get

294.4 / 16 = 18.4 = other side length
2 (18.4) x 2 (16) = 68.8cm perimeter
