Answer:

Rise over Run, the slope in this graph would be 3/4

Step-by-step explanation:

You count the number of spaces it takes to move up, then you move right, towards the line. You write the rise number on top and the number moving right (run) on the bottom, (rise over run).

I hope this helps you, if not let me know in the comments :)

Write a system of equations to describe the situation below, solve using elimination.

Sedbober [7]

Answer:

The cost of hardbook is $9 and cost of paperback is $5.

Step-by-step explanation:

Let x be the price for hardback book and y be the price for paperback book.

Mr. Yamamoto purchased 42 new hardcover books and 64 new paperback books, which cost a total of $698.

We can write the equation as:

$42x + 64y = 698$

He also purchased 42 new hardcover books and 58 new paperback books, which cost a total of $668.

We can write the equation as:

$42x + 58y = 668$

We have to use the elimination method to solve the two equations.

We eliminate x by subtracting the two equations.

$42x + 64y-(42x + 58y) = 698 - 668\\\Rightarrow 6y = 30\\\Rightarrow y = 5\\42x + 64(5) = 698\\\\\Rightarrow x = \displaystyle\frac{698 - 64(5)}{42}\\\\\Rightarrow x = 9$

Thus, the cost of hardbook is $9 and cost of paperback is $5.

Section J in an arena has 20 rows.Each row has 15 seats.All tickets cost $18 each.If all the seats are sold how much money will

bekas [8.4K]

Answer:Total amount of money collected for arena J = $5400

Step-by-step explanation:

Section J in an arena has 20 rows.

Each row has 15 seats. This can also means that section J has 20 rows and 15 columns. The rows and column form a rectanglar shape. This means that the total number of seats would be number of rows × number of columns

= 15 × 20 = 300 seats

All tickets cost $18 each. If all the seats are sold, that means that each seat cost $18 each.

Total amount of money collected for arena J would be total number of seats × the cost per seat.

Total amount of money collected for arena J = 300 × 18 = $5400
