70 flowers were planted in all.
Step-by-step explanation:
Let,
Tulips = t
Daises = d
Lilies = l
Total tulips planted = 42
She planted 2 times as many tulips as daises.
t=2d
Putting t=42
[tex]42=2d\\2d=42[/tex]
Dividing both sides by 2
[tex]\frac{2d}{2}=\frac{42}{2}\\d=21[/tex]
And 3 times as many daisies as lilies.
d=3l
Putting d=21
[tex]21=3l\\3l=21[/tex]
Dividing both sides by 3
[tex]\frac{3l}{3}=\frac{21}{3}\\l=7[/tex]
Total flowers planted = Tulips + Daisies + Lilies
Total flowers planted = 42 + 21 + 7 = 70
70 flowers were planted in all.
