Answer:
7.2 cm
Step-by-step explanation:
For the similar triangles, the ratio of the length of the bottom side to the right side is the same:
bottom/right = (x cm)/(6 cm) = (12 cm)/(10 cm)
x cm = (6 cm)(12/10) = 7.2 cm
_____
Technically, x = <em>7.2</em>, not <em>7.2 cm</em>.
x | y
5 2
6 5
7 8
8 11
yes, because each x value has exactly one 7 value
First we should change these mixed numbers into improper fractions:


We can find the number of crates used by dividing the total amount of electrical supplies by the amount that each crate can hold:

/

*

So now we know that
Otto used 7 crates.
