Lincoln middle school plans to collect more than 2,000 cans of food in a food drive. so far, 668 cans have been collected. write an inequality to find numbers of cans the school can collect on each of the final 7 days of the drive to meet this goal. identify what your variable represnts.

Step-by-step explanation:

Given:

Lincoln middle school plans to collect more than 2,000 cans of food

They have already collected 668 cans

To Find:  WRITE AN INEQUALITY to find numbers of cans the school can collect on each of the final 7 days of the drive to meet this goal.

Solution :

Let x be the number of cans collected on each day.

Cans collected on 7 days = 7x

Since they already collected 668 cans

So they have total cans = 7x+668

We are given that they are required to collect more than 2000 cans

⇒

Thus this is the required inequality to find the numbers of cans collect on each final 7 days of drive

Now,

⇒

⇒

⇒

⇒

Thus they require to collect more than approx. 191 cans each day

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
