Answer:
(3,2)
Step-by-step explanation:
The system is
x + y = 5
x -y = 1
Add the equations to eliminate y
2x = 6----->x=3
Substitute this value in any equation
3+y = 5----->y=2
The solution is (3,2)

Answer:
standard form of given equation is 5x - 8y = -3
Step-by-step explanation:
Standard form of linear equation is Ax + By = C
First we remove the denominator 8
We multiply the whole equation by 8
So equation becomes
8y = 5x + 3
Now we move 5x to the left hand side, we subtract 5x on both sides
-5x + 8y = 3
Now we remove the negative side from -5x by dividing the whole equation by -1
5x - 8y = -3
Answer:
The volume is 22.44 cubic inches
Step-by-step explanation:
The formula for the volume of a sphere is
We know the diameter, but we can easily convert this into the radius by dividing it by 2, since the diameter is twice as long as the radius.
3.5/2 = 1.75
Now we can find the volume.
So, the average volume of a clementine is 22.46 cubic inches
The closest option you have is 22.44 so if you round it that should be your answer.
Answer:
X= 2
Step-by-step explanation:
10 + x = -12
X = 12 - 10
X = 2
