So percent means parts out of 100
x%=x/100
so we jsut have to find
(red)/(total)
add 23+52+34343434+61+30=34343600
red=52
52/34343600
divide out
0.0000015141103/1
multiply by 100/100
0.00015141103/100=0.00015%
make bottom number 100
26/100=26%
answer is 26%
A perfect cube is a number that is a cube of an integer.
As we multiply the matrices on the left-hand side,we have;
x+3y=5---eq1
x+4y=6---eq2
eq1-eq2
-y=-1
y =1
Subsitution of y=1 in eq1,
x+3(1)=5
x+3=5
x=5-3
x=2
