Answer:

LEFT

k + 3 = 20,

k = 17

RIGHT

3x + 5 = 32,

k = 9

Step-by-step explanation:

For the left side, you have k + 3 on one side equaling 20, so the equation is

k + 3 = 20

To solve is as follows

k + 3 = 20

  - 3    - 3

     k = 17

For the right side,

You have 3 x's and 5 1's right? Adding them together will equal 32 (Other side

So your equation is 3x + 5 = 32

To solve is as follows

3x + 5 = 32

    - 5     -5

      3x = 27

Dividing both sides by 9 we get x = 9

Reasoning; you want to cancel out everything with x so that you got x alone on one side.

Hope this helps, if not comment on this telling me which step I did that you dont understand and I'll explain it.

MO is twice as long as MN. NO= 36 cm. What lengths must NM be between in order for MNO to be formed?
Nataliya [291]

Answer:

Length of NM is 36 cm

Step-by-step explanation:

Length of MN + Length of NO = Length of MNO (Or only MO)

X + 36 = 2X

2X - X = 36

X = 36 cm

Thus, length of MN is equal to length of NO i.e 36 cm

The line MNO has point N, that bisect it into two equal half.

Thus, the line MNO has two parts

Total length of line MNO = MN + NO = 36 + 36 = 72 cm

On Monday, Florencia's hair was h centimeters long. She got a haircut on Tuesday, so her hair was only 75%, percent of the lengt
topjm [15]

Answer:

Step-by-step explanation:

Alright, lets get started.

Florencia's length of hair on Monday = h

Now on Tuesday after haircut, her length is 75 %  of the length it was on Monday.

So, length of hairs on Tuesday will be = h * \frac{75}{100}

So, length of hairs on Tuesday will be = h*0.75

Means , length of hairs on Tuesday will be = 0.75 h

So after haircut, Florencia's hair was 0.75 h.   :  Answer

Hope it will help :)
