Answer:
D ![\left[\begin{array}{ccc}-6&-6.5&1.7\\-2&-8.5&19.3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-6%26-6.5%261.7%5C%5C-2%26-8.5%2619.3%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation:
Two matrices are equal when they
- have the same sizes (so options A and B are false)
- have equal corresponding elements (so option C is false, because -6≠6, -6.5≠6.5, 1.7≠-1.7 and so on)
If in option D the second row is 2 -8.5 19.3 , then these matrix is equal to the given.
I don’t have the time for my birthday but I’m just asking for a little
Hello!
First you have to find how many sections of blue ribbon makes 1 meter
1/5 * 5 = 1
It takes 5 sections of blue ribbon to make one meter of blue ribbon
Multiply this by the sections of red ribbon
1/2 * 5 = 2.5
The answer is 2.5 meters of red ribbon for every meter of blue ribbon
Hope this helps!
