Hi! I've tried this problem a couple times but am still stumped :( Can you help?!

ANSWER:

$X\text{ = }\begin{bmatrix}{12} & {-4} & {-2} \\ {-8} & {-13} & {8} \\ {8} & {15} & {18}\end{bmatrix}$

EXPLANATION:

Given:

$U\text{ = }\begin{bmatrix}{1} & {3} & {-5} \\ {2} & {14} & {11} \\ {-8} & {0} & {5}\end{bmatrix}\text{ V =}\begin{bmatrix}{13} & {1} & {-7} \\ {-6} & {1} & {9} \\ {0} & {15} & {23}\end{bmatrix}$

Since U and V are Matrices with equal dimensions(3 x 3 matrix), and

X + U = V.

To solve for X, we have:

X = V - U

$\begin{gathered} X\text{ = V - U} \\ X\text{ = }\begin{bmatrix}{13-1} & {-1-3} & {-7-(-5)} \\ {-6-2} & {1-14} & {19-11} \\ {0-(-8)} & {15-0} & {23-5}\end{bmatrix}=\text{ }\begin{bmatrix}{12} & {-4} & {-2} \\ {-8} & {-13} & {8} \\ {8} & {15} & {18}\end{bmatrix} \end{gathered}$ $X\text{ = }\begin{bmatrix}{12} & {-4} & {-2} \\ {-8} & {-13} & {8} \\ {8} & {15} & {18}\end{bmatrix}$

hot dogs are sold in packages of 10 and hot dog buns are sold in packs of 8 Tommy wants to know the least number of packs of hot

enot [183]

Answer:

4 packs of hotdogs, 5 packs of buns

Step-by-step explanation:

In this case, we need to find the LCM, least common multiple, of 8 and 10 to find the least number of packs of hot dogs and buns that Tommy needs to buy.

The LCM of 8 and 10 is the smallest number that is both divisible by 8 and 10. One way we can find this is by checking all the multiples of 10 in ascending order to see if they are divisble by 8:

10 is not divisible by 8

20 is not divisible by 8

30 is not divisible by 8

40 is divisible by 8!

Therefore, Tommy will need to by 40 buns and 40 hotdogs. Since buns come in packs of 8 and hot dogs come in packs of 10, we can divide to get the number of packs Tommy should buy respectively:

$40$ ÷ $10=4$ packs of hotdogs
