1/x=6/21

What you need to do is set it up as a proportion.  1 cup to 6 cups cake mix, x cups to 21 cups cake mix.  

21/6 is 3.5

So 3.5 cups of water to 21 cups of cake mix (:

Hope this makes sense!

The recipe calls for 1 cup of water for every 6 cups of cake mix.
So, if you take 21 and divide it by 6, which is 3.5, that's how much water you should add (in cups).

A fence is being built around a rectangular garden. The length of the garden is 35 feet, and the total fencing used to enclose t
liraira [26]
The garden's width is 45. We know this because
35 \times 2
(length)
35 \times 2 + 2x = 160 \\
35x2 is 70 and you need to neutralize that by taking away 70 from both sides.
160 - 70 = 90
2x = 90
Now divide by 2 on both sides to neutralize the 2 times x.
90 \div 2 = 45
meaning that leaves us with
x = 45

The point A(-8, 6) is translated using T: (x,y) → (x + 5. y - 4). What is the distance from A to A'?
Vsevolod [243]
Translated means the points are moving across the plane without rotating or changing shape. In this case, the x-coordinate would be moving up 5 (x + 5) and the y-coordinate would be moving to the left 4 (y - 4).

A is (-8, 6). A' is the result of the translation from this point. The results of the solution above in A is the point (-3, 2) = A'.

Now you must find the distance between these two coordinates. To find the distance you must use the distance formula: √<span>(x2 - x1)^2 + (y2 - y1)^2. Since you now have two points, A and A', plug these into the distance formula.

</span>√(-3 - (-8))^2 + (2 - 6)^2
√5^2 + (-4)^2
√25 + 16
√41

The distance from A to A' is √41.
