21x - 27 = 0 (add the 3x + 18x together since they’re like terms)

21x = 0+27 (move the -27 to the other side of the = and when you do the sign will become the opposite eg “-“ will become “+” and a multiply will become a divide)

x = 27 ÷ 21

x = 1.29 or 9/7

what you have to do it try and get x on its own on one side of the = so you shift all the other things to the other side i guess

Georgia [21]
1. broccoli, cauliflower and carrots
2. squash, carrots and cauliflower
3. cauliflower, carrots and squash
I'm not going to type all the combination. So basically you have to multiply the vegetables by the number 3. So 3 x 4 is 12. Therefore he could do it in 12 different ways. Hope this helped.

Find the distance between the points<br><br> (1,8) and (-3,8)
Vilka [71]

Answer:

<h2>4 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

From the question we have

d =  \sqrt{ {(1 -  - 3)}^{2} +  ({8 - 8})^{2}  }  \\  =  \sqrt{ ({1 + 3})^{2} } \\  =  \sqrt{ {4}^{2} }  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  =  \sqrt{16}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>4 units</h3>

Hope this helps you
