What is the answer to: 7(w+2)+0.5w=5

1 answer:

6 0

First, distribute the 7:

7w + 14 + 0.5w = 5

Combine like terms:

7.5w + 14 = 5

7.5w = -9

Divide both sides by 7.5 to solve for w:

w = -9/7.5 = -1.2

The answer is -1.2

The length of a rectangle is 3cm greater than its width. the perimeter of the rectangle is 34cm. find its length.

mamaluj [8]

Answer:

10cm

Step-by-step explanation:

The formula for perimeter is:

$P=2(l+w)$

Let the width of the rectangle be x then the length would be...

3+x

Now, let's plug these values into the equation and solve. (Note we are also given perimeter is 34 cm):

$34=2(x+3+x)\\34=2(2x+3)\\Distribute\ the\ 2\ to\ each\ term\ in\ the\ parentheses\\34=2(2x)+2(3)\\34=4x+6\\Subtract\ 6\ from\ both\ sides\\4x=28\\Divide\ both\ sides\ by\ 4\\x=7$

And since the length is x+3 then it is...

x+3=7+3=10cm

Which is an equation of the line that goes through the points ( 4, 1) and

Aloiza [94]

Answer:

none of the above

Step-by-step explanation:

You can try the points in the equations (none works in any equation), or you can plot the points and lines (see attached). <em>You will not find any of the offered answer choices goes through the given points</em>.

___

You can start with the 2-point form of the equation of a line. For points (x1, y1) and (x2, y2) that equation is ...

y = (y2 -y1)/(x2 -x1)·(x -x1) +y1

Filling in the given points, we get ...

y = (3 -1)/(2 -4)·(x -4) +1

y = 2/(-2)(x -4) +1 . . . . . simplify a bit

y = -x +4 +1 . . . . . . . . . simplify more

y = -x +5 . . . . . . . . . . . slope-intercept form
