If im correct the answer would be 4, hope i could help out.
8 x - 4 (5 - x) = -44
mutiply the bracket by -4
(-4)(5) = -20
(-4)(-x)= 4x
8x-20+4x= -44
8x+4x-20= -44 ( combine like terms )
12x-20= -44
move -20 to the other side
sign changes from -20 to +20
12x-20+20= -44+20
12x= -44+20
12x= -24
divide both sides by 12
12x/12= -24/12
Answer: x= -2
Commutative property: a + b = b + a
3 + 5 + 7 = 3 + 7 + 5 = 10 + 5 = 15
Another basic one
(1/2)^2*1/2*(1/2)^3=
(1/2)^6 =
1\2^6=1/64
if in decimal: 0.015 but i would prefer 1/64 if i was the teacher :)
We can find the volume of the cylinder using the next equation:
Where h represents the height and r represents the radius.
The radius is the half value of the cylinder. Then :
r=d/2
r=7yd
r=3.5yd
Replacing:
Hence, the volume is 98π yd³
98π yd³=307.9
The answer is decimal form is 307.9 ( The value is rounded to the nearest tenth).
