99(x-77)=99(x+88)
99x-7623=99x+8712
99x-99x=8712+7623
0=670824.no solution as x becomes 0
Where is the graph? Could you attach it somewhere
X - (1/5x + 1/2x + 1/4x)
= x - 19/20x
= 1/20x
= 0.05x (Written in decimal)
No, Josh is wrong. it should be 0.05x and not 0.5x
Answer:
nCr = n! / (r!)(n-r!).
Step-by-step explanation:
That would be nCr = n! / (r!)(n-r!).
A quick way of working these out is as follows:
Take 7C4:
this is 7*6*5*4/4*3*2*1 Cancelling out the 4 and 3*2:
= 7*5
= 35.
15C12 = 15C(15-12)
= 15C3
= 15*14*13 / 3*2*1
= 5*7*13
= 455.
146.74 because 42% of 253 is 106.26, and take that away from 253 = 146.74
