A group of adults and students went on a class trip to Washington, DC. The number of male students was 1 more than 7 times the n
Helga [31]
In equation, let x be the number of male students
a be the number of adults
y be the number of female students.
x= 7a+1
a= x/7 -1
y= x/2 or (7a + 1)/ 2

a + b = 82, let b be the number of students.
a + (x + y) = 82
a + [7a+1 + (7a+1)/2] = 82
a + [{2(7a+1) + 7a+1} / 2] = 82
a + [(14a +2 + 7a +1) / 2] = 82
a + [(21a + 3) / 2] = 82
(2a+ 21a + 3) / 2 = 82
(23a + 3) / 2 = 82
23a + 3 = 164
23a = 164 -3 
23a = 161
a = 7

x = 7(7) +1, 49+1 = 50 male students
y=x/2, 50/2, 25 female students

50(male students) + 25(female students)  + 7 (adults) = 82

Subtract (8.4 x 108) − (9.5 x 106).
Step2247 [10]

Based on the fact that the expressions to be subtracted have the same base, the result is 8.305 x 10⁸.

<h3>What is the result of the subtraction?</h3>

The first number in standard form is:

= 8.4 x 10⁸

= 840,000,000

The second number in standard form is:

= 9.5 x 10⁶

= 9,500,000

The result is:

= 840,000,000 - 9,500,000

= 830,500,000

In scientific notation this is:

= 8.305 x 10⁸
