Yesterday was Mother's Day. You sent your mother a bunch of lilies and a box of chocolates as a gift totaling $43. The
chocolate costs you $13 and the price of a lily flower was $3.
How many lily flowers did you buy for your mother?
lily flowers.

10 lily flowers

Step-by-step explanation:

subtract the total by the price of the chocolates

43-13=30

you get $30 the total price of flowers, each flower was $3

divide $30 (the total price of flower) by $3 (price of each flower)

30/3

the answer is 10 flowers

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
