1/3+1/9= 4/9, which is a rational number. 1/3 is equal to 0.333333, which is equivalent to 1/3, while 1/9 is equal to 0.1111111. By adding we get 0.44444444, which is equal to 4/9.
23. 3^2 is 9 and 9 x 2 = 18 + 5 = 23
Answer:
(0,2) is one solution of the solution set of the equation x + 3y = 6.
(0,2) is not an element of the solution set of the equation -x + y = 8.
Step-by-step explanation:
We have the system of equations, x + 3y = 6 and - x + y = 8.
Now, we have to check whether the solution set for that system of equations or not includes the point (0,2) or not.
Here, the equation x + 3y = 6 is satisfied by the point (0,2).
Hence, (0,2) is one solution of the solution set of the equation x + 3y = 6.
But the equation - x + y = 8 is not satisfied by the point (0,2).
So, (0,2) is not an element of the solution set of the equation -x + y = 8.
The cost of one sweatshirt is $19.
Step-by-step explanation:
Let,
Cost of one pair of jeans = x
Cost of one sweatshirt = y
According to given statement;
5x+2y=233 Eqn 1
3x+4y=193 Eqn 2
Multiplying Eqn 1 by 2
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 7
Putting x=39 in Eqn 2
Dividing both sides by 4
The cost of one sweatshirt is $19.

Answer:
70 is a more reasonable partial quotient because 70 * 4 = 280 which is closer to 296, without going over it, then 4 * 50 = 200 which is further away.
