I believe it would be B.
Logically, it’s the only one that makes sense,
As 9x10= 90
None of the others have any way to divide or multiply up to the area,
So yes, B.
Answer:
x = -3
Step-by-step explanation:
f(x) = 4x + 11
f(x) = -1
Substitute -1 for f(x)
-1 = 4x + 11
Subtract 11
-12 = 4x
Divide by 4
-3 = x
x = -3
Target: ratio of pizza places / person < 0.01
<span>The
population of 15 blocks of the north side of town is 221 people per
block, but there are already 32 pizza places in the area.
population = 15*221 = 3,315
ratio: 32 pizza places / 3315 people = 0.0097 pizza places per person
Which indeed is less than 0.01 => this area is good for their purpose.
The population
of 22 blocks of the south area is 150 people per block, and there are
28 pizza places in the area.</span>
population: 22*150 = 3300
ratio: 28 pizza places / 3300 people = 0.00085 which is also less than 0.01
Both places meet the target of less than 0.01 places per person, but the south area seems better than north area.
Ya pretty much find the decimal form of 1/10 and thats it
By doing cross multiplication.
