Answer:
17
Step-by-step explanation:
You plug the variables in into their respective location, resulting in
7(6) - 5(5).
Now, you just multiply, getting
42 - 25
42 - 25 is 17

Answer:
x = 9
Step-by-step explanation:
Isolate the variable. Note the equal sign, what you do to one side, you do to the other. Multiply 3 to both sides.
(x/3)(3) = 3(3)
x = 3(3)
x = 3 * 3
x = 9
x = 9 is your answer.

Hello!
The volume of a cone is Volume = 1/3πr²h.
V = 1/3π(10)²(9)
= 1/3<span>π100(9)
</span>= 1/3<span>π900
= 300</span>π cm³
Therefore, the volume of this right cone is 300<span>π cm</span>³.
The correct answers are:
- The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true.
- The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false.
Further explanation:
Given equations are:
2x-y = -5
x+3y = 22
We have to check whether the given statements are true or not. In order to find that we have to put the points in the equations
Putting the point in 2x-y = -5

Putting the point in x+3y=22

The point satisfies the first equation but doesn't satisfy the second. So,
1. The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true.
This statement is true as the point satisfies the first equation
2. The ordered pair (7, 19) is a solution to the second equation because it makes the second equation true.
This Statement is false.
3. The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false.
This statement is true.
4. The ordered pair (7, 19) is a solution to the system because it makes both equations true.
This statement is false as the ordered pair doesn't satisfy both equations.
