Huh this gives out no information to answer
147 is not a prime number 147= 49 * 3
49 is divisable by 7: 49= 7 * 7
7 is not divisable by anything
Answer:
![X = \begin{bmatrix} - 4 & 1 \\ - 2 & - 7\end{bmatrix}](https://tex.z-dn.net/?f=%20%20X%20%3D%20%3C%2Fp%3E%3Cp%3E%5Cbegin%7Bbmatrix%7D%20-%204%20%26%201%20%5C%5C%20-%202%20%26%20-%207%5Cend%7Bbmatrix%7D)

An algebraic expression that represent how much Mr. Green paid in all is 3(m + 1) + d
<h3 /><h3>Pet fish</h3>
The following represents the items bought
- Each bag has m mollies and 1 bala
- He bought 3 of these bags
The expression that represents the items in a bag is:
![Bag=m + 1\\](https://tex.z-dn.net/?f=Bag%3Dm%20%2B%201%5C%5C)
He bought 3 bags.
So, the total spent on pet fish is:
![Total =3(m + 1)](https://tex.z-dn.net/?f=Total%20%3D3%28m%20%2B%201%29)
<h3>Fish food</h3>
A box costs d dollars.
This means that, the total amount Mr Green spent in the store is:
![Total =3(m + 1) + d](https://tex.z-dn.net/?f=Total%20%3D3%28m%20%2B%201%29%20%2B%20d)
