Can someone please help
Leona [35]

Answer:

each hamburger costs $3.50

Step-by-step explanation:

he spent $13 in total and bought one hot dog for $2.50 and 3 hamburgers but we don't know the price of one hamburger so we could represent it by the equaton,

2.50 + 3h = 13 now solve for x

-2.50           2.50

3h = 10.50

h=3.50

check:

2.50+3(3.50)=13

2.50+10.50=13

13=13

Which matrix is equal to P + Q?
Afina-wow [57]
Answer: 
\begin{bmatrix}-1.1 & 9.5\\-5.7 & 0.8\\6.1 & 0.7\end{bmatrix}

------------------------------------

Add up the corresponding elements

Row1,Column1: 6.1+(-7.2) = -1.1
Row1,Column2: 1.9+7.6 = 9.5
Row2,Column1: -7.5+1.8 = -5.7
Row2,Column2: 2.2+(-1.4) = 0.8
Row3,Column1: 3.8+2.3 = 6.1
Row3,Column2: -1.4+2.1 = 0.7

So that's why the answer is 
\begin{bmatrix}-1.1 & 9.5\\-5.7 & 0.8\\6.1 & 0.7\end{bmatrix}
