Carla enjoys collecting baseball cards Her album contains 115 pages . Each page holds 9 baseball cards How many baseball cards are will there be in her album in all?

1035 cards

Step-by-step explanation:

the total number of baseball cards can be calculate by multiplying amount of pages and how many cards each page can hold.

115*9=1035 cards

1035 cards

Step-by-step explanation:

Step 1: State what is known

The album contains 115 pages

Each page has 9 cards

Step 2: Assume the pages are full, calculate how much cards are in the album

115 pages x 9 cards per page = 1035 cards

Therefore there are 1035 cards in the album

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
