8.5b.
7a= 5a +3b
-5a -5a
2a = 3b
/2
a= 1.5b
Solve by substitution and you get;
8.5b=8.5b
Because of the lack of constants in the equation there isn't a definite answer.

 7a - 2b = 5a +   b

<u>       +2b          + 2b</u>

 7a = 5a + 3b

<u>-5a    -5a </u>

2a  =  3b

There were 8,651 deaths and 14,662 births reported in Hillsborough County in the year 2000. If there were 998,948 people living
alexdok [17]

Crude birth rate is all the time reported per 1000 living people.

To compute for this, the formula is number of births x 1000 divided by the estimated population at midyear. So plugging in the values given:

14,662 x 1000 divided by 994,948

= 14662000 / 994948

= 14.68 per 1000 living people.

Answer:

<h2>82 in²</h2>

Step-by-step explanation:

The median of the four numbers a, b, c and d. Where a ≤ b ≤ c ≤ d:

\dfrac{b+c}{2}

We have

84in², 72in², 80in², 84in² → 72in², 80in², 84in², 84in²

The median:

\dfrac{80+84}{2}=\dfrac{164}{2}=82\ in^2
