Answer: You can multiply the top equation by -1 to eliminate the x variable.
And the solution is (2,4/3) in case you need it.
Step-by-step explanation:
2x + 3y = 8
2x + 6y = 12
If you multiply the upper equation or down equation by one, you will be able to eliminate the x variable.
-1( 2x + 3y) = -1(8) New equation: -2x -3y = -8.
Add the new equation you got by multiplying the top equation by -1 to the bottom equation.
Add them: -2x -3y = -8
2x + 6y = 12
3y = 4
y = 4/3
You can now input the value for y into the one of the equations and solve for x.
-2x - 3(4/3) = -8
-2x -4 = -8
+4 +4
-2x = -4
x = 2
Answer: I think it is 8 meters because 83 cm in meters is 0.83 meters :)
Step-by-step explanation:
Answer:
1386
Step-by-step explanation:
V=πr²*h
V=22/7*7²*9
V=1386
Given :
Length of parade , 
.
Breadth of parade , 
.
5 people can fit into a 
area.
1 mile = 5280 ft .
To Find :
The size of the crowd.
Solution :
Area of parade ,
Also , 5 people can fit in area .
So , number of people fit in A is :
Therefore , 95040 can fit in the parade .
Hence , this the required solution .
Just by simply adding the two quantities you can get the net change. $67.12 +(addition sign because we want the net change) $2.56= $69.68. The last number is the net change!
