Answer: x = 3, y = 6
Solution:
4x - 3y = -6
2x + y = 12
Rearrange the terms
4x - 3y = -6
y = 12 - 2x
Substitute
4x - 3(12 - 2x) = -6
Solve the equation
x = 3
Substitute
y = 12 - 2 x 3
Solve the equation
y = 6
Write the solution
x = 3
y = 6
Answer:
Lol sorry I didnt fully process it the area is 39.25 cm^2
Step-by-step explanation:
a = πr²
a=3.14(3.5^2
3.14(12.5)
39.25
Answer:
30.2 aka C
Step-by-step explanation:
The formula for the area of a circle is A = pir^2. Knowing this we can create the equation A = 3.14(3.1)^2. Following PEMDAS square 3.1 to get 9.61. Then you multiply 9.61 with 3.14 to get 30.1754. When you round to the nearest tenth you get 30.2.
Answer:
(x,y)=(2,-3)
Step-by-step explanation:
6x+2y=6
7x+3y=5
Multiply both sides by 3
18x+6y=18
7x+3y=5
Multiply both sides by -2
18x+6y=18
-14x-6y=-10
Eliminate one variable by adding the equations
4x=8
x=2
Substitute the value of x to get y
6(2)+2y=6
y=-3
x=2
y=-3
