Answer:
Step-by-step explanation:
From 3 1/2 (= 7/2) to 6 cups of flour (basically 6 divided by 7/2) is 12/7
now you multiply 3/4 times 12/7
it equals to 36/28
simplify each by 4
36/4 = 9 and 28/4 = 7
9/7
as a mixed number it is 1 2/7
Answer:
True
Step-by-step explanation:
The sum of cubes a^ 3 + b^ 3 = (a + b) (a ^2 − a b + b^ 2 )
We need to determine if 216x^3 is a cube and 64 is a cube
216 = 6*6*6
216 x^3 = (6x) ^3
and 64 = 4*4*4 = 4^3
So 216x^3 +64 = (6x)^3 + 4^3

Answer: AI is 8, Rob is 18, and Bert is 36
Step-by-step explanation:
Ok, so the sum of their age is 62. Bert is x2 of Rob. Also someone is 10 years older than AI, lets assume Rob is the guy that is 10 years older. x+y+10+(z times 2)=62. So lets solve it. 62-10=52. 52=x+y+(z times 2). Now if you think about it x and y is the same, because the 10 is already minused. So it's now x*2+z*2=52, if you assume it now, z is x+10. So now it is 52=x*2+(x+10)x2. Now we break out the brackets so its x*2+x*2+20=52. Lets simplify it. x*4+20=52, lets swift the 20 the the other side. x*4=52-20, x*4=32. 32/4=8 so 8 is x. Now we know AI is 8, Rob is 18, and Bert is 36!
