Answer:

x = 30

Step-by-step explanation:

10% fat = 0.1x

x = the solution, what we want to find

120 grams of 20% fat = 0.2 * 120

What we want is mixture of 18%

So....

0.1x + 0.2 * 120 = 0.18 (x + 120)

Solve:

0.1x + 24 = 0.18 (x +120)

0.1x + 24 = 0.18x + 21.6

24 = 0.08x + 21.6

x = 30

Write an equation for the translation of x ^ 2 + y ^ 2 = 25 by 6 units left and 3 units down.
Aliun [14]
The equation would be: (x + 6)^2 + (y + 3)^2 = 25

This equation will produce a circle. If you add the numbers inside the parenthesis to be squared, you can center of the circle. Thus, translating the shape.

D is the midpoint of CE. If CD= 2x+10 and DE =3x-18, find x and CE<br><br> x=<br> CE=
Veseljchak [2.6K]

Answer:

<h2>x = 28</h2><h2>CE = 132</h2><h2 />

Step-by-step explanation:

|<------------- CE -------------------->|

C-------------------D-------------------E

       2x + 10              3x - 18

2x + 10 = 3x - 18

2x - 3x = -18 - 10

-x = -28

x = 28

CE = 2x + 10 + 3x - 18

CE = 2(28) + 10 + 3(28) - 18

CE = 56 + 10 + 84 - 18

CE = 132
