The seventh grade class is putting on a variety to raise money . it cost $700 to rent the banquet hall that they are going to use . if they charge $15 for each ticket , how many tickets do they need to sell in order to raise at least $1,000

The class needs to sell at least 20 tickets

Let x be the number of tickets that need to be sold in order to add up to $1000

Using the equation $700+$15x>=$1000

Subtract 700 from both sides and then divide each side by 15 to get 20.

d is ur answer hopes this i dont really know how to explain it to u.

given expression is

we have radical  

we need to select an option that has same radical

(a)  

this expression has cube root instead of square root . so it is not a like radical.

(b)

y is included inside the radical. so it is not a like radical.

(c)

this expression has cube root instead of square root . so it is not a like radical.

(d)

5 is inside the radical square root. so it is   a like radical.
