The length of a rectangle is three centimeters more than twice the width. The perimeter is 78 centimeters. Define a variable and write and solve an equation to find out how long and wide the rectangle is? I need to find the length? how?

Answers

L = 2w + 3
The perimeter equation is:
2L + 2W = 78
Put what L equals in to find w:
2(2w + 3) + 2w = 78
6w + 6 = 78 ( I did a short cut)
6w = 72
6w/6 = 72/6
W = 12
At this point, put width back into the first equation to find the length
L = 2(12) + 3
L = 27

One linear equation is defined by the points (2, 4) and (1, 1), while the other is defined by the points (2, -2) and (-1, -5). Which point represents the solution to this system of equations?

Answers

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:

m: It's the slope

b: It is the cutoff point with the y axis

Equation 1:

Go through the points:

So, the line is:

We substitute a point:

Finally the line is:

Equation 2:

The equation is:

Substituting a point:

Finally the equation is:

Equaling both equations:

We look for the value of y:

The point (-1, -5) is system solution

As Shilo has a jar of jelly beans and has a ratio of 32:56 then if the ratio is the same and she gives his fiend a 7 pink jellybean then the number of the green jelly beans would be.

  • It actually depends on the whole bag of the jelly beans up my taint with the 10 in pink jelly-beans and 32 blue ones to start.
  • There came out only 5 pink and 16 half-chewed blue ones. Hence the rest remaining are the green beans.
