A rectangle is 12m longer than it is wide. Its perimeter is 68m. Write and equation and show steps to find its length and width.
Galina-37 [17]

Answer:

  length: 23 m; width: 11 m.

Step-by-step explanation:

The perimeter of a rectangle is twice the sum of its length and width, so that sum is 34 m. Then you can write two equations in length and width:

  l + w = 34

  l - w = 12

Adding these together gives you ...

  2l = 46

  l = 23 . . . . . . divide by 2

Then the width is

  w = 23 -12 = 11

The length and width are 23 m and 11 m, respectively.

Solve 4m plus 2n equals 5n for m.
RSB [31]

Answer:

m = (3/4) n

Step-by-step explanation:

4m + 2n = 5n

The subtraction property of equality states that we can subtract 2n from both sides to isolate the m and its coefficient to get

4m = 3n

The division property of equality states that we can divide 4 from both sides to isolate only the m (we divide by 4 because anything divided by itself equals 1) to get

m = (3/4) n

Can someone help me with number 3 please there is 3 answers!!
AlekseyPX

Answer:

m<J = 83

m<L = 97

m<M = 97

Step-by-step explanation:

The corners across (left to right/right to left) from each other of a trapezoid are always equal.

So, it would be like this:

Angle J is equal to angle K

Angle M is equal to angle L

See how they are across from each other?

Therefore, Angle J will be 83 degrees.

To find the other 2 angles subtract 83 from 180

180 - 83 = 97

So, Angle L and M are 97 degrees.

To check your answer you can add up all the corners and they should equal 360 degrees:

83 + 83 + 97 + 97 = 360

360 = 360
