Sonya plans to spend at least 15$ on berries to make pies. Strawberries are on sale for 3$ per pint, and blueberries are on sale for 1$ per pint. SHe plans to buy at least 8 pints of berries. Which system of inequalities can be used to determine the number of pints of strawberries, x, and the number of pints of blueberries, y, that Sonya should buy.
A=(3x+y≥15)
(x+y≥8)
B=(15≥3x+y)
(8≥x+y)
c=(15≥3x+y)
(x+y≥8)
D=(3x+y≥15)
(8≥x+y)

B)

15 ≥ 3x + y

8 ≥ x + y

Step-by-step explanation:

Strawberries= 3x

Blueberries= y

At least symbol= ≥

15 ≥ 3x + y (Plans to spend AT LEAST $15 so this has to be 15 ≥)

8 ≥ x + y (Plans to spend  AT LEAST 8 pints so this has to be 8 ≥)

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
