if we have 20 less than 4 times a number, we would be subtracting 20 from the 4 times the number. therefore, the only one that represents 20 less than 4 times a number is $\boxed{4x-20}$
The surface area of a sphere is 4$\pi$r$^2$, and the diameter is 8, so the radius is 4, so we plug in 4 for r, and we get:
$4\pi\cdot16=\boxed{64\pi}$
I suppose this is where this question arises:
I would say B if you 'associate ' the .85 and the .15 together
the answer is $\boxed{B}$ because 0.85+0.15=1, and subtracting -1/3 is much easier that way.
They were not mine either !
No it doesnt. 2+2 = 4.
To find the area of a parallelogram, simply multiply Base x height, which is 4.9 x 9.6 = 47.04
maybe, probably, who knows?
parallelogram area: height x base
9.6 x 4.9 = $\boxed{47.04}$

With vertex at 0,0 and including point 12, -18 it obviously opens downward (dome shaped)
Vertex form parabola
y = a (x-0)^2 + 0
y = a x^2 sub in 12 , -18
-18 = a (12^2)
a = -18/144 = - 1/8
y = -1/8 x^2
15+15/2=22.5
22.5+22.5$\cdot$7/100=24.075 rounded to $\boxed{\$24.08}$ or $\boxed{B}$
Initially there is 5 R out of total 13
5/13 choose a repub
now there is 4 out of 12 R left
4 /12 choose a R
now there is 3 outof 11 R left
3/11 choose R
5/13 * 4/12 * 3/11 = ............

The pizza circumference would be 6pi inches, which is approximately 18.8495 = 18.8 rounded to the nearest tenth.
The range is [a,a + b].
The area is sqrt(3)/2.
3 isn't a factor of 34 because 34/3 = 11 1/3 which is not a whole number...
It works out to A/[XYZ] = 17/27.
thank you!
3 isn't a factor of 34 because 3 doesn't divide into 34 evenly :)
34 ÷ 3 ≈ 11.33
3a + 4b = 20
12a + 16b = 80
As you can see, if you multiply the first equation by 4, they are both the same.
This means there are no solutions (D) for this system of equations :)
Re-arrange into y = mx + b form where m = slope
y = 7/3 x -7 slope = 7/3
