I believe the answer to your question is 23
Linear combination method just means to add the equations so that one variable with cancel. In this case the a values are already set up so that they will cancel.
2a + 3b = 1
-2a + b = 11
4b = 12
b = 3
now put 3 back into either of the original equations and solve for a.
2a + 3(3) = 1
2a + 9 = 1
2a = -8
a = -4
(-4,3)
Answer:
I believe the answer is C :)
Step-by-step explanation:
This is easy!
The overall amounts of flips is 32, which puts it on the bottom. It gave you a number of times you flipped it and received 8.
Giving us 8/32
which is 1/4 and in percentage form it is 25%
Answer:
Density of steel = 80.73 gm/
Step-by-step explanation:
The figure is made up of cuboid and square pyramid.
Height of cuboid, h = 9 cm
Length of cuboid, l = 6 cm
Width of cuboid, w = 6 cm
Volume of cuboid is given by the formula:


Density of Wood ,
= 0.68g/
We know that formula of Density is:


Putting the values:

Total weight = 
970 = 220.32 
= 749.68 gm
Volume of pyramid is given as:

Base is a square with side 6 cm

Density of Steel/Pyramid:
