Answer:
19,500 - (1,000 x 12) = X
Brianna earns $ 7,500 more than Lisa per year.
Step-by-step explanation:
Given that Brianna earns $ 19,500 per year and Lisa earns $ 1,000 per month, to write a numerical expression that represents how much more Brianna earns per year than Lisa the following calculations and equations must be performed:
19,500 - (1,000 x 12) = X
19,500 - 12,000 = X
7,500 = X
Thus, Brianna earns $ 7,500 more than Lisa throughout the year.
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

Dividing both sides by 2

And 3 times as many daisies as lilies.
d=3l
Putting d=21

Dividing both sides by 3

Total flowers planted = Tulips + Daisies + Lilies
Total flowers planted = 42 + 21 + 7 = 70
70 flowers were planted in all.
