Allison has 5 time as many baseball cards as football cards. in all, she has 120 baseball and football cards. how many baseball cards does allison have?

100

let the number of football cards be x then she has 5x baseball cards

the total cards she has is 120, hence

x + 5x = 120

6x = 120 ( divide both sides by 6 )

x = 20

Allison has 20 football cards and 5 × 20 = 100 baseball cards

b=baseball cards

f=football cards

b=5f    she has 5 times as many baseball cards as football cards so we multiply the football cards by 5 to make them equal

b+f=120   there are 120 football and baseball cards total

5f+f = 120  substitute 5f everywhere you see a b

6f = 120  combine like terms

f=20  divide by 6

there are 20 football cards

b=5f

b=5(20)

there are 100 baseball cards

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

central angle of a triangle has the same measure as its intercepted arc.
