Answer:
8.
Denote the equation : y = ax + b
Use the first 2 values of x and y in table:
3a + b = 21
5a + b = 35
Subtract the 2 equations:
=> 2a = 14 => a = 7 => b = 21 - 3 x 7 = 0
=> The solution is y = 7x
9.
Denote the equation : y = ax + b
Use the first 2 values of x and y in table:
5a + b = 17
10a + b = 22
Subtract the 2 equations:
=> 5a = 5 => a = 1 => b = 17 - 5 x 1 = 17 - 5 = 12
=> The solution is y = x + 12

First we will subtract 16 acres from total land 349 acres.
349-16=333 acres
Now divide 333 by 3
Answer will be 111 lots of 3 acres.
Perimeter of rectangle = 2(l+w)
So, 54cm = 2(l+9cm)
=> 54cm = 2l + 18cm
=> 54cm - 18cm = 2l
=> 36cm = 2l
=> 36cm/2 = l
=> 18cm = l

<u><em>Tyrell started with $541.</em></u>
First you must know the total amount of money spent on the games. For that Tyrell bought 6 video games this summer and each game cost 27 dollars. So to calculate the amount spent, the number of games purchased must be multiplied by the price of each one:
6 video games* 27 dollars each game= 162 dollars
So Tyrell spends 162 dollars.
On the other hand, you know that Tyrell had 379 dollars left after he bought the video games. This indicates that after spending $ 162 on video games, there were $ 379 left over. To know the amount of money that Tyrell had, you must add the amount spent on games and the money that was left over:
162 dollars + 379 dollars= 541 dollars
So, <u><em>Tyrell started with $541.</em></u>
