3x+9=36
with 2 times 9kg and 18kg is the solution:

I:2x+y=36
II:y=x+9

if you substitute y of II into I:

3x+9=36
3x=27
x=9
-> 2 boxes with 9kg and 1 with 9+9=18 kg

2*9+18=36kg in total

so the third option/Rashid is the solution

I need help on ratio of x-coordinates and ratio of y-coordinates
ad-work [718]

Answer:

Ratio of x-coordinates:

\frac{-1}{-2}=\frac{1}{2}

\frac{2}{4}=\frac{1}{2}

\frac{2}{4}=\frac{1}{2}

\frac{-2}{-4}=\frac{1}{2}

Ration of y-coordinates:

\frac{2.5}{5}=\frac{1}{2}

\frac{1}{2}=\frac{1}{2}

\frac{-2}{-4}=\frac{1}{2}

\frac{-2}{-4}=\frac{1}{2}

Step-by-step explanation:

The table is asking for the ratio of x-coordinates for each point (A, B, C and D) for both the image and pre-image.  The ratio is the image 'x' or 'y' value ÷ the pre-image 'x' or 'y' value.  Each ratio should be expressed in simplest form and should show the same pattern of dilation, or same scale factor.  In this case, the second figure is 1/2 the size of the original figure.

What is the radius in centimeters of a circle that has a circumference of 16 centimeters
Whitepunk [10]
If I did this correctly all you hade to do is work in reverse. 
1.) Divide 16 by pi (3.14) To get the diameter.16/ 3.14 =5.095541401 or 5.1
2.) Since Diameter is just the radius doubled divide 5.1 by 2. 5.1 /2 = 2.55
3.) Plug it in, use the 2pir equation to see if it works.  2X3.14X2.55= 16.014 or 16.
                     I hope this helps, let me know if you need further explanation.

Match the absolute value expression to its correct distance from zero on the number line.
Kaylis [27]

Answer:

  • 7.1
  • 6.9
  • 5
  • 5.7

Step-by-step explanation:

The value of the expression is its distance from zero. The absolute value is the positive value without any minus sign.

  |-7.1|=7.1\\\\|2.7+4.2|=|6.9|=6.9\\\\|4-9|=|-5|=5\\\\|-3.1+8.8|=|5.7|=5.7
