If you spend at least $50(including shipping) at an online store, you receive a $10 gift card. You want to purchase CDs that cost $12 each. If shipping costs $5, write and slice an inequality to find the number of CDs you must buy to receive the gift card.

5 CD's

Step-by-step explanation:

5(#of CD)*12($ for each CD)=60+5 for shiping= 65-10(Gift card)= 55

It says at least 50 so you could not do 4 CD which would be less than $50 spent

Hope this helps :)

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
