The dance committee of pine bluff middle school earns $72\$72 $72 from a bake sale and will earn $4\$4 $4 for each ticket they sell to the spring fling dance. the dance will cost $400\$400 $400 . write an inequality to determine the number, tt t , of tickets the committee could sell to have money left over after they pay for this year's dance.

Step-by-step explanation:

Let t be number of tickets sold by the committee.

We have been given that the committee earns $4 for each ticket they sell, so money earned from selling t tickets will be 4t.

We are also told that the committee earns $72 from a bake sale, so the total money earned by school will be equal to amount earned from t tickets and the bake sale.

As the dance will cost $400, so the total money earned should be greater than 400. We can represent this information in an inequality as:

Therefore, the inequality represents the number of tickets the committee could sell to have money left over after they pay for this year's dance.

Let us solve for t by subtracting 72 from both sides of our inequality.

Let us divide both sides of our inequality by 4.

Therefore, the number of tickets sold by dance committee should be greater than 82 to have money left over after they pay for this year's dance.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
