Maria designs and creates costumes for a living. A few months ago, she bought 5 spools of ribbons and 12 bags of sequins for $44.75 total. This month, she bought 19
spools of ribbon and 12 bags of sequins for $111.25 total. What was the cost of each spool of ribbon and each bag of sequins?

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

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
