No signs of draggin stuff
so PEMDAS
so wha yyou woul ddo first is see if parenthasees can be simplified
it cannot
so next we do multiply or distribute the 9
9(x+2)=9x+18
so now we have
9x+18=90
then we do subtraction
of 18
9x=72
divide 9
x=8
so order is multiplication then subtraction then division
Answer:
The Total number of peoples went to street fair including all three days is 785 peoples .
Step-by-step explanation:
Given as :
The number of people went to fair on Friday = F = 215 peoples
The number of people went to fair on Saturday = Sa = 163 more people than on Friday
So, The number of people went to fair on Saturday = The number of people went to fair on Friday + 163 peoples
∴, The number of people went to fair on Saturday = 215 + 163 = 378 peoples
And
The number of people went to fair on Sunday = Su = 192 peoples
So , The Total number of peoples went to fair = The number of people went to fair on Friday + The number of people went to fair on Saturday + The number of people went to fair on Sunday
So, The Total number of peoples went to fair = 215 peoples + 378 peoples + 192 peoples
∴ The Total number of peoples went to fair = 785 peoples
Hence , The Total number of peoples went to street fair including all three days is 785 peoples . Answer
V= x*(10-2x)(8-2x)
for greatest volume, differentiate v w.r.t x and equate to 0,
dv/dx= (10-2x)(8-2x) + x(-2)(8-2x)+ x(10-2x)(-2)=0
you get x from solving the quadratic equation. volume will be max at that x
Answer:
the mistake is x and y x is 6 and y is 4 so it would be 5x6 and 4^2 divide by 2
Step-by-step explanation:
the right one is 5x-y^2 divide 2
5x6-4^2 divide 2
5x6-16 divide 2
30-8
