Find the given elements of matrix D<br> Please help!!!
TEA [102]

Answer:

Element wise subtraction.

Step-by-step explanation:

Matrix Subtraction is done element wise.

Therefore, D = \[  \left[ {\begin{array}{ccc}   3 & 1 & 0 \\   -1 & 2 & 4 \\9 & 7 & -2  \end{array} } \right]\] - \[  \left[ {\begin{array}{ccc}   5 & 2 & -4\\   1 & 12 & 3 \\ 11 & 3 & -2  \end{array} } \right]\]

This becomes:

\[   D =  \left[ {\begin{array}{ccc}   -2 & -1 & 4 \\    -2 & -10 & 1 \\    -2 & 4 & 0  \end{array} } \right]\]

Now, $ d_{11} = -2 $

$ d_{12} = -1 $

$ d_{13} = 4 $

$ d_{21} = -2 $

$ d_{22} =  -10 $

$ d_{31} = -2 $

Write the word sentence as an equation. Then solve the equation.
Nana76 [90]

Answer:

see below

Step-by-step explanation:

9 is the difference of a number n and 7.

Let's break this down.

"is" represents the equal sign.

"the difference" represents subtraction.

9 = n - 7

Now let's solve the equation.

9 = n - 7

Add 7 to both sides.

16 = n

Hope this helps!

Albert wants to buy two pomegranates and some peaches • The price of one pomegranate is $1.59. • The price of peaches is $1.19 p
viktelen [127]

Answer:

He can buy 5 pounds of peaches.

Step-by-step explanation:

2 pomegranates cost $3.18 so, subtract that from $10.00 and you get $6.82. Multiply the different number of pounds with the cost per pound until you go over $6.82. Then go back a pound and multiply. 5 pounds times $1.19 equals $5.95.
