Barbra bought 2 greetings cards at $1.50 each, 3 packages of wrapping paper at $2.29 each and 1 roll of ribbon for $1.45. How much did she spend altogether?

$11.32

Step-by-step explanation:

Greeting Cards = $1.5 x 2 = $3

Wrapping Paper = $2.29 x 3 =  $6.87

Ribbon = $1.45 x 1 = $1.45

So now we must add the totals to figure out how much money Barbra spent in total.

$3 + $6.87 + $1.45 = $11.32

why can't you?

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
