I am confused.. Where is the question? This is just information but what is the actual question. Then I can help you :)
We need to know the density of Marble City, hence we know the density of Pebble City.
MC density = population/area
MC density = 52,348/125
MC density = 418.784 people/miles
From the question, we know that the two cities have the same population density.
PC density = MC density
PC density = 418.784 people/miles
Use the density formula to figure out the dimension of PC
PC density = population/area
418.784 = 85,312/(l × w)
(l × w) = 85,312/418.784
11.8 w = 85,312/418.784
11.8 w = 203.7
w = 203.7/11.8
w = 17.2
The closest value of x is 17 miles
Answer:
Step-by-step explanation:
10x + 25y = 370
y = x + 5
10x+25(x+5)=370
10x+25x+125=370
35x=370-125
x=245/35
x=7 which is the number of dimes
x+7= 7+5= 12 which is the number of quarters
So you have 12 quarters. That means you have 7 dimes.
Answer:
Step-by-step explanation:
Multiply the denominators so you will have common denominators.
Then 5x + 11 = A(x+3) + B(x+1)
So 5x + 11 = x(A+B) + 3A + B
The only thing that has x in right is (A+B)
So A+B = 5
And 3A + B = 11
So 2A=6
And A=3
B = 5 - 3 = 2
