Angelina has five cakes. She wants to cut them into 2/5 pieces. How many pieces will she be able to cut?
Licemer1 [7]
<span><u><em>Answer:</em></u>
She will be able to cut them into <u><em>12.5 pieces</em></u>

<u><em>Explanation:</em></u>
We know that the total number of cakes is 5 cakes and that the portion of each piece would be </span>\frac{2}{5}<span>.

To know the total number of pieces she can divide, we would simply divide the total number of cakes by the portion of each cake as follows:
number of pieces = </span>\frac{5}{ \frac{2}{5}}
<span>
number of pieces = </span>\frac{25}{2}
<span>
number of pieces = 12.5 pieces

Hope this helps :)

The triangles are similar.
Elenna [48]

Answer:

x = 12

Step-by-step explanation:

The triangles are similar so we can use ratios

4x+12      32

-------  = ------------

15             8

Using cross products

(4x+12) *8 = 15 * 32

(4x+12) *8 = 480

Divide each side by 8

(4x+12) *8/8 = 480/8

4x+12 = 60

Subtract 12 from each side

4x+12 -12 = 60-12

4x = 48

Divide by 4

4x/4 = 48/4

x = 12
