Plug in numbers. if originally, it was V=1/2 * 1 * 1 * 2=1
<span>tripling the dimensions would be V=1/2 * 3 * 3 * 6=27 </span>
<span>it would be 27 times larger. this could also be found by 3^3, just as doubling would render 2^3
</span>
Replace each occurrence of x by 7. So we have:-
7^2 + 3 / 7 - 9
= 52 / -2
= -26 answer
If 5y-10=0 it would equal 2. Add ten to both sides and then divide 5 to both sides which leaves you with y=2
10cm=10 * 10^-2 = 10^-1 meters
so its 2 meters + 0.1 meters = 2.1 meters
The correct answer among the choices listed above is the second option. <span>The following system of equations is equivalent. This is because when written in the same form, one equation will yield to the same equation as the other.
</span>y = -1/3x +2/3
<span>2x + 6y = 4
</span>6y = 4 - 2x
y = 2/3 - 1/3x
<span>y = -1/3x +2/3 </span>
