5x34= 170
68+76= 144
170+144= 314
To find the value of a variable you must know the basics of pre-Algebra.
Example:
2x+9=39
To find he answer of this you must subtract 9 from both sides
Then you are left with…
2x=30
Since 2x=30 means 2 times x equals 30
You can divide 2 from both sides to find the answer
Which is…
x=15
1/8÷3/8
multiply by the inverse
1/8 x 8/3 = 8/24 or 1/3
The volume of a cone is V= (1/3)pi r²h
it was given
h=12cm
radius=3cm
the volume of the first cone is V1= 1/3)pi r²h1
where h1= h/2=6cm
so its volume is V1=1/3)xpix3²x6=56.52cm^3
and since the two cones are identical so V1=V2=<span>56.52cm^3,
we need </span><span>56.52cm^3 or salt </span>
