Since <em>x</em> is the number of 14-year periods, the first thing we do is divide 28 years by 14. 28/14=2. Now we use that in our function,
.
There will be 220 foxes after 28 years.
Answer:
Step-by-step explanation:
z = 3
2y + z = 1
2y + 3 = 1 {substituting z =3}
2y = 1 -3
2y = -2
y = - 2/2
y = -1
2x +3y +2z = 13
2x + 3 * (-1) + 2*3 = 13 { {substituting z =3} and y = -1}
2x -3 + 6 =13
2x + 3 = 13
2x = 13 - 3
2x= 10
x = 10/2
x = 5
Answer:
7.17 cm
Step-by-step explanation:
If the width is x, the length is twice this = 2x
And
Perimeter = 2 (W + L)
so
Perimeter = 2 ( x + 2x)
Perimeter = 2 (3x)
Perimeter = 6x
43 = 2 ( x + 2x )
43= 2 ( 3x)
43 = 6x
= 7.17 cm
Hope this helps i'm pretty sure this is how you do it :-)
The total solution will include 17.5 cup of vinegar 0.5 cups of rubbing alcohol, and 2 cup of water which is a total of 35 cups of solution. Sofie will need 6 total containers to hold all of the solution.
<h3>
Number of container</h3>
1 cup of rubbing alcohol:
1 cup of rubbing alcohol=1÷1/2
1 cup of rubbing alcohol=2
Cup of alcohol needed:
Cup of alcohol needed=1+1/2+16
Cup of alcohol needed=17.5 cups
Total cups:
Total cups=17.5×2
Total cups=35 cups
Number of container:
Number of container=1+35/5
Number of container=1+5
Number of container=6 containers
Therefore the total solution will include 17.5 cup of vinegar 0.5 cups of rubbing alcohol, and 2 cup of water which is a total of 35 cups of solution. Sofie will need 6 total containers to hold all of the solution.
