Agroup of friends is buying popcorn and soda at the movies. they want to buy at least 4 items, and can spend up to $20.00. popcorn costs $3.00 each and soda costs $1.00 each. let x represent the number of popcorns purchased, and y the number of sodas. which system of inequalities represent this situation

x + y ≥ 4

3x + y ≤ 20

Step-by-step explanation:

Since 'x' represents the number of popcorns and 'y' represents the number of sodas, the amount they want to purchase is at least 4 items.  So, the sum of these two must be greater than or equal to 4:

x + y ≥ 4

Given that they only have $20.00 to spend and the cost of popcorn is $3 and a soda costs $1, the sum can be at most $20:

3x + y ≤ 20

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
